WHARF DESIGN: FOGGY MORNING PERSPECTIVE: PART 2

This was a fun image to work on and the breakdown is relatively straight forward. The big poetic moves such as fog and coloring come towards the end which is typically the case with images like this. There was a lot of prep in Photoshop such as refining textures, lighting, and adding entourage. But once those elements were in, some serious experimenting began to generate the final mood of the image. I have continued to tweak the image from the last post, focusing mostly on color. Because of the way this image was set up, the image is very flexible and could easily be manipulated into a dusk shot or even a night shot. However, for this breakdown, I will stay with the morning shot. 

 

1. Composition

An often overlooked element of an architecture illustration is composition. Going into this image, I wanted to capture the scope of the project as much as I could showing the length of the pier as well as its relationship to the water and city. I also wanted to express the topographical elements of the design so I brought the camera as close to the water as I could while still being able to see the deck lighting. The image is positioned so that the horizon sits right on the lower 1/3 of the image. I knew I would be recreating the sky in Photoshop so I simply added more height to the canvas in Photoshop to shift the horizon to the lower 1/3 of the page. The center of the foreground building's long facade is placed directly on the left hand 1/3 line of the image. After finishing the image, I realized the real focal point was actually the green wall in shadow. It would have been ideal to place this directly on the left hand 1/3 line instead of the other facade. This could have been accomplished by cropping the shot, but I wanted to keep as much of the docks and city towers as possible, so I left it as is. 

 

2. Base Rendering

I'm not going to spend too much time here but I thought I would give some basic settings that I used in V-Ray. Before I rendered, I edited the model to help with the reading. For example, little things like adding slight overhangs at each step to create shadow really helped  to define the step edge and topography of the wharf. I also added lights embedded into the pier by creating a material in Sketchup, painting that material in each location of the light, and then telling that material to emit light in V-Ray. However, running out of time to tweak the lights to my satisfaction, I abandoned the rendered lights and decided to paint in the lights using Photoshop instead. 

I used an HDRI for the sky and background seen below which was downloaded from viz-people.com. Along with the HDRI sky and background, I also turned back on the V-Ray sky with an intensity lowered to 0.02 to generate stronger light hitting the surfaces. The biggest advantage of V-Ray over Kerkythea for me is the ambient occlusion settings. This really helps pull out the detail and depth in the base rendering. The AO settings used in this scene were: Amount- 1.0, Subdiv- 16, and Radius- 40. 

Other than that, I used the physical camera to control the exposure and set the output resolution to 4500px X 2520px.

Above, the final base rendering from V-Ray. 

 

3. Alpha

The first step in Photoshop often begins with separating out the background from the base file. Most rendering programs will render an alpha channel making the selection of the background much easier. Removing the background allows for better flexibility when adding the sky and background buildings.

 

4. Background Texture

Next, I searched Google for images of the surrounding context. I then begin sampling the buildings, desaturating the texture, and applied them to the base rendering. I used a range of layer blend modes, but "Multiply" seemed to work the best in most cases. I applied the textures one surface at a time allowing me to match perspectives for each facade.

 

5. Lights

Knowing that thick fog was going to be added later, I like the idea of the lights in the city bleeding through. I spent a little time painting in light and punching up the lights around the design. I go into greater detail explaining the process of painting in light in my PAINTING LIGHT tutorial .

 

 

The design calls for lights imbedded in the deck of the wharf. As mentioned above, I had originally rendered the lights in V-Ray, but didn't have time to refine the settings. I ended up painting in the light which allows me to hone in the look that I am going for. The process is very similar to adding the lights in windows described above. The important thing here is adding that little bit of glow to each one.

 

6. Entourage

People are important for understanding scale in a design. Therefore, it is crucial that they are shown at the correct size. I often throw in some 2d people in Sketchup at different locations of the site, then export a 2d graphic of the view, and bring that image into Photoshop. This provides a clear reference for proper scaling when I begin to insert high res images of people. Since the scene has low light, I darkened the people to have more of a silouette effect. This minimizes the destraction of bright colored clothing or improper lighting. It's also important to note the reflections on the ground. To some, this may be a subtle move, but this helps to "ground" the people and set them into the image. Shadows have the same effect in daytime scenes. Without shadows or reflections, the people will appear to float and seem out of place. Awhile ago, I put together a tutorial on adding people which can be seen HERE.

 

7. Sky

The more time I spend working on architectural illustrations, the more I realize the importance of the sky. This often will make or break the illustration. In this case, I was looking for something that would work well with a foggy scene but not distract  from the design. I found some images that gave me the flexibility to experiment with the softness of the reading. I ended up desaturating the sky textures and overlaying them on the background which then picked up the blue tones already in the base rendering. I then feathered out the edges so that the sharper texture of the clouds remained in the center of the image drawing attention back to the design.

 

8. Bring on the Fog

For many people, this part can be intimidating. In reality, there is nothing to it. The most important thing to remember is to slowly layer on the paint. This means setting the brush opacity low, below 10%. Rendering programs like V-Ray can render out a channel called "Z-Depth" which renders a gradient based on how far an object is from the camera. The problem I have with this channel is that it is too perfect. Especially for a foggy scene, the fog is inconsistent in density. I was looking for a loosness and softness that the Z-Depth channel couldn't provide. I therefore manually painted in the fog. I did two passes shown below. The first pass was to highlight the light coming from behind the city creating a glare look. The second pass represented a denser more encompassing fog. I switched the fog color to red to better explain where it was placed. In this case, the imperfection works to my advantage.  You can see a more in-depth explanation at my "Adding Depth Via Fog" tutorial .

 

9. Color Overlay

I almost always end with some kind of color overlay. The color overlay does two things. It takes the color range of all the different photoshopped images and brings them together into a more cohesive look. Color overlays also allow me to quickly cool or warm and images changing the entire feel of the illustration in a few seconds. In this case, I was going for an early morning atmosphere, so I looked at several color options. I tested a red overlay at a very low opacity first and then looked at a blue overlay which I ultimately ended up going with. I also really liked the image completely desaturated. The black and white seemed to pull out the texture of the sky and enhance the drama. For more on color overlays, visit THIS POST.

 

 


Moving forward, I plan to render out a few more views exploring some different graphical styles not yet addressed on this site. I'm extremely excited about picking apart this design and seeing what kind of new imagery can be extracted. More on this later...

WHARF DESIGN: FOGGY MORNING PERSPECTIVE: PART 1

 

Modeler: Sketchup

Renderer: V-Ray

Post Processing: Photoshop

Final Output Size: 4500 px x 2520 px

 

The Boston Long Wharf perspective illustrations are underway. This first illustration is one of the more important ones because it is describing the entire design and its relationship to the water and the city. An early morning fog scene has been on my to-do-list for a while and this view/project seemed like a perfect opportunity to give it a try. One of the toughest things I found working on an illustration like this was keeping the overall color saturation to a minimum. I have a tendency to amp up the color in past illustrations through lots of color overlays. With this image, I constantly was going back and desaturating layers to maintain that early morning mood.

This illustration took me a little longer than the others for a few reasons. I have been designing and building the 3D model as I go. Typically, I spend a few hours when I can after work during the week on the modeling. It got to the point on Friday where I had to buckle down and make some design decisions and stick with them for the final illustrations. The good thing was once these decisions were made, I was able to quickly brute force model and get things where I needed them to start setting up the rendering.

I have attached some of the screen shots of the Sketchup model below.

 

The other thing that absorbed some of my time was setting up the file to render. Anyone that follows this site knows I prefer to spend most of my time in Photoshop. However, with this shot, I decided to invest a little more time preparing the textures and lighting. V-Ray was used for this image instead of Kerkythea, a rare occurrence on this blog. Below are some screen shots of the raw rendering output from V-Ray.

I kept most of the surrounding context largely untextured. This area of Boston is highly photographed online and I knew I would be overlaying images of the background buildings on top of the base rendering. For that reason, I rendered the context gray allowing me to overlay the photography but still maintain the light and shadow of the base rendering.

 

You may have noticed the title says, "Part 1". I plan to salvage what I can of this 4th of July weekend and pick back up in the next post with an in-depth break down of the post processing in Photoshop. These types of illustrations are fun to work on and I think the workflow would be interesting to see.

Favorite Architectural Cutout and Texture Resources

Architecture visualization can consume a lot of resources and time if you're not careful. With the tediousness of Photoshop and renderings calculating through the night, spending more that 20 minutes searching Google images for a specific texture or image can become a breaking point for many. Any way to save time in this field is a big advantage, especially in school. The thing is, there are a lot of free resources online that have already put in the hard work so that you don't have to. Many of these sites were life savers going through architecture school. 

Below are some of my favorites websites containing free cutouts and textures. Some of the resources made the list because of their clear organization of the information. Often, there are very specific demands of a project or client that require lots of time online searching. These sites offer smart labeling and clear categorizing that makes finding specific items painless.

 

1. SKALGUBBAR 


 

Skalgubbar offers up a large library of high resolution cutout people in PNG format. The people are often in unique situations which don't work for all illustrations. At the same time, the unique positions can also help add a bit of character to some less exciting images. Either way, I enjoy the "tumblr-like" display allowing you to quickly browse through a lot of images.

 

 

2. IMMEDIATE ENTOURAGE

 

 

Immediate Entourage is another great site to find a large collection of cutout people. The resolution of the cutouts are hit or miss, but the library is comprehensive. What is even better, I.E. also provides many cutouts of vegetation. Everything is well labeled so it is easy to find what you need. 

 

 

3. GOBOTREE

 


Gobotree is a large and growing library of free images and cutouts created by the people at Vyonyx. By using the categories drop down at the top of the page, you can find extensive libraries of cutout people and vegetation to quickly populate an illustration. I especially like their sky collection and visit it often. I'm impressed with how this site is progressing and hope they can keep it growing. You do need to register for a free account which limits downloads to 50 images a month.

 

 

 

4. Mr CUTOUT

 

 

Mr Cutout provides extremely high res cutouts from a descent size library. The problem is that once registered, you are limited to 2.5 mbs a day. Just a few downloads can consume the entire daily allowance. This can be limiting with only a few days to produce an illustration. However, the quality of the cutouts are some of the best and can be a good resource for some of the close-up foreground elements.

 

 

 

5. XOIO AIR

 

 

This site offers full cutout collections of people in specific situations. Examples include a collection of office scenes, coffee scenes, people scene from above, people scene from below, etc. Green screens are used meaning the cutouts are of the highest quality. XOIO also provides many other collections of 3d models and backgrounds that can be helpful as well.

 

 

 

6. CGTEXTURES

 


Probably one of my all-time favorites, I visit this site every time I am working on a new illustration. CG Textures is a huge database of jpg textures, many of which are tileable. This works great for texturing in Sketchup as well as in Photoshop. What I appreciate the most about this site is its incredible organization and in-depth library. It's my go-to place when I need to find very specific and unique textures. The free account allows you to download 15 mbs a day.

 

 

7. TEXTURER

 

 

Similar to CG Textures, Texturer does a good job of organizing the images. However, few of the textures are tileable. Though this limits my use, there are still many useful textures to be found once I'm post processing in Photoshop.

 

 

8. SWTEXTURE

 

 

What I like about SWTexture is the size of the tileable textures. When used in a 3D model or in Photoshop, the tiling is barely noticeable. The blog focuses on commonly used materials so you will be hard pressed to find anything unique or specific. However, the textures that are provided are of great quality and worth checking out.

 

 

9. FLYINGARCHITECTURE

 

 

Not only a great blog, Matúš of FlyingArchitecture provides several V-Ray textures which include bump and displacement maps. Though the textures are created for V-Ray, you can use just the diffuse images in your 3d model and in Photoshop if needed. 

 

 

10. RENDERTEXTURES

 

 

This site is a pleasure to browse and beautifully designed. Rendertextures is a spinoff of FlyingArchitecture so the images are of similar quality and also contain bump and displacement maps. Beyond that, the information is well organized and easy to navigate. This is not a large collection but a good suppliment to what you may already have.

 

 

11. TONY TEXTURES

 

 

While there are some free cutouts, I personally like Tony Textures because of their many high res texture images. Though most are not tileable, the viz images such as skies, ground planes, water, etc.  go a long way in Photoshop. I often explore this site if the other resources fail to deliver. 

 

I'm always looking for more resources so if there are any that I missed, send me an email or leave a comment. You can never have enough entourage.

HIGH RES SITE PLAN

 

In the previous wharf post, I discussed black and white texture studies that focused on pattern and ground plane elements throughout the wharf. The above image builds off of those studies introducing color and material. Site plans are extremely useful in the design process and I wanted this one to be somewhat malleable as I tweak things. 

The wharf is on a strong axis with Boston's Old State House. I wanted to be able to study this connection as well as the wharf's relationship to the dense city fabric. The site plan was therefore setup to include this information which meant creating one of the highest resolution images I have ever done. The above image tops out at 10,000 pixels tall. Typical illustrations for me are around 4,000 to 5,000 pixels on the longest edge. The high resolution was needed to be able to study different spaces and textures up close. However, this will also allow me to crop out several close-up images for presentations allowing me to get lots of mileage out of this one site plan.

To manage the high resolution, I rendered out two 5000x2300 images seen below. To speed things up, I didn't worry about adding texture or material in the Kerkythea rendering. I knew I would be experimenting with textures in PS and didn't want to have to worry about baked in materials. I only needed the shade and shadow so I rendered some clay models and stitched them together in Photoshop.

 

 

The final PSD file can be broken down into three main sections. I used an aerial image to get much of the existing texture information of the roads, buildings, etc. The aerial was overlayed on top of the clay model with a lowered opacity. I then took the black and white texture studies from the previous post and worked that information into the new site plan. Since all of the line work elements were separated and grouped in the previous PSD file, it was easy to make adjustments and extend the ground plane elements to the Old State House. Finally, I added texture, color, and vegetation on top of everything.

 

With the site plan far along, I'm ready to start diving into some perspectives. I hope to get going with those in the upcoming posts along with some portfolio spreads. I'm thinking about setting up a vertically oriented portfolio layout as this is a more common layout with the online printers. More to come on this later.

BEST OF TUMBLR GALLERY

It was a little over a year ago that I started a visitor gallery tumblr page in an attempt to generate a another place on the internet for architecture visualization inspiration. It has been exciting to see so many unique styles and methods submitted week after week. I curate the gallery which means not every illustration submitted will get posted to the tumblr page. As a matter of fact, only about 1/3 of the images make it to the tumblr page. Total, there have been 260 illustrations posted since its inception.

I thought I would highlight some of my favorites in no particular order. These images were chosen for many different reasons: uniqueness, composition, color palette, style, technique and execution. Each of these illustrations combine those characteristics to create a mood and personality that draw in the viewer. Without knowing more about the projects, they are very engaging images on their own and a great source of inspiration.

DIAGRAMS: TEXTURE STUDY

The last few posts have been focused on diagramming the existing conditions of the site. In this latest post, I have shifted to studies for the new design. The overall concept and form of the Sketchup model is established, but now I am interested in exploring texture. I trid to keep things abstract before getting too specific with thoughts of actual materiality and color. The above black and white approach was one way for me to keep thinking conceptually without losing myself in the details. As much as this image looks "finished", the workflow was very much a loose and explorative process. Many iterations and ideas were tested. Changes in line weights, shadows, and hatches helped define hierarchy and texture qualities. 

From here, I expect the illustration to continue to evolve as the project is refined and more decisions on form and material are made. The process of creating an image like this in Photoshop is "sketchy" in nature which lends itself well to exploring ideas along side 3D modeling. Later on down the road, I may begin introducing color as ideas of materiality become more concrete.

Below is a quick breakdown of how the image was created. Everything was made in Photoshop except for the initial line work and shadows which were exported from my Sketchup model. For the most part, I used the Brush Tool to create most of the elements. I also applied drop shadows and strokes to the elements when needed.

 

1. Sketchup Line Work

 

2. Shadows Exported from Sketchup. 

I adjusted the levels to take the shadows from grey to black.

 

3. Water Poche

I darkened the water slightly to better clarify the relationship of water to land.

 

4. Profile Lines and Guide Lines 

Thick profile lines were added to punch up important elements of the design.

 

5. Abstract Boats

Simple rectangles with shadows were used to represent the boats in an abstract manner. These were then copied many times to imply movement.

 

6. Thick Dashed Line Work

The thick dashed lines represent an abstraction of several elements of the existing site. Density and location were determined by topographical changes and potential pedestrian traffic.

 

7. Thin Dashed Line Work

A second layer of thinner dashed lines were added. These are hierarchally weaker than the thick dashed lines and could represent a change in material among other things.

 

8. Poche

A final layer of shading was added to highlight potential locations of green space.

 

Though the workflow has been broken down into a very systematic explanation, the actual process of creating this image was not as clear cut. As mentioned above, it was a very iterative process where all of the element were slowly built up together through additive and subtractive means. There was a lot of copying, pasting, transforming, and scaling. Less focus was placed on craft and more on a relaxed and experimental process.

DIAGRAMS: HATCH PATTERNS

This post is also a follow up from many emails asking me to explain the diagonal line hatching used the site analysis diagrams. There are two methods in Photoshop that I know of that can create the diagonal line hatch seen in the image above. Both options use a relatively fast workflow and are easy to execute.

OPTION A: Google Image Overlay

A1. This option involves simply going online and finding a hatch pattern. In this case, I Google searched "diagonal lines" and found several images that would work. The images do not need to be large because I can copy the texture many times to create a much larger texture for what I need. 

If you do need to copy a small image many times, hold down the "Alt" key ("Option" on Mac) and drag the image using the "Move" tool. This quickly duplicates the layer. Once you have all of the layers aligned forming a larger image, they can be merged into one layer by selecting all of the individual layers in the layers palette, right click on one of the layers, and choose "Merge Layers". 

A2.  Next, the white background needs to be removed. This is easily done by selecting the new hatch layer, then choosing "Multiply" in the layer blend mode drop down in the layers palette.


OPTION B: Create a Custom Pattern

A second option to create a hatch is to define a custom pattern which can offer much more flexibility. This method will often generate cleaner line work than what can be found on the web. One other thing to note is that many PS patterns can be found online through websites like Brusheezy which can be imported into Photoshop.

B1. I want to create my own custom pattern. To do this, I first need to create a new document in Photoshop by going to "File>New". I set up the new document to be 12x12 pixels, however this size can change depending on your needs. Also, double check to make sure the background contents is set to "Transparent". 

B2. Next, select the "Rectangular Marquee Tool" and make a selection crossing the entire document. I made my selection 2 pixels high. The Rectangular Marquee Tool should snap to each pixel making it easy to determine how many pixels are being selected.

Choose the "Paint Bucket Tool" on the left and also select a black paint color. Then, fill the selection. 

B3. The pattern is ready, so now it needs to be saved into Photoshop as a pattern. Choose "Edit>Define Pattern". In the dialogue box, give the pattern a descriptive name and choose "OK". 

B4. To apply the pattern to the illustration, first create a new layer and move it to the top of the layers palette. Then, select the "Paint Bucket Tool". In the paint bucket options at the top, be sure to select "Pattern" in the drop down and set the Opacity to 100%.

To the right of the pattern drop down, there is another drop down which will show a thumbnail of all of the saved patterns. Choose the pattern created in the steps above.

With these options set, use the paint bucket to fill the page making sure it is on the new layer.

B5. Since this pattern was applied on its own layer, it can be rotated 45 degrees to create diagonal lines. Choose "Edit>Transform>Rotate" and hold down "Shift" when rotating to snap to 45 degrees.

Use Masks to Hatch Specific Elements

The hatch patterns are rasterized on their own layer meaning the hatch can simply be erased using the eraser tool. However, applying a mask will allow for editing later on down the road if changes need to be made. 

1. Apply Mask

To apply a mask, select the hatch layer and choose the "Add a Mask" icon at the bottom of the layers palette.

2. Make Selections 

Next, use the "Polygonal Lasso Tool" to select the areas of the illustration that will be filled with the hatch pattern. 

3. Inverse the Selection

I want the selection to be what I want erased, therefore I am going to inverse the selection. Choose "Select>Inverse" at the top.

4. Fill the Mask

Finally, choose the "Paint Bucket Tool", check that the opacity is set to 100%, and also that the drop down is set to "Foreground". 

The mask works by using gray tones to determine what parts of the image will appear or not appear. Black paint erases the image. White paint will reveal the image. I don't want the hatch to appear in the part of the image that is selected, therefore I want to choose black paint.

Double check that the layer mask is selected which is the white box next to the layer image in the layers palette. Using the paint bucket tool, fill the selection with black paint. This will "erase" away the hatch pattern where the selection was made. White paint can be used to bring back the hatch pattern later if changes are needed.

Below, the final result using patterns and masks to give a little more texture to the image and help define important areas of the diagram.

DIAGRAMS: PEDESTRIAN PATHS

I received a lot of emails asking if I could explain how I created the pedestrian paths diagram in the previous post. To generate the line work, there are many ways this could be done. In the past, I probably would have used the spline tool in CAD. The line work could also easily be created in Illustrator. However, not many people know about or use the pen tool in Photoshop. It's similar to the pen tool in Illustrator but with some minor differences. In this case, I will be using the pen tool to create a path that I can tell the brush tool to follow. 

1. Setup the Brush settings

I need to first set the brush settings because this is what I am going to use to add a stroke to the path created in the next step. The settings in this step will determine the thickness of the line as well as the color, hardness, and opacity. I chose a hard brush, 6 pixels big, at 100% opacity, and with black paint. You may need to draw a few lines to determine if you have the correct size.

2. Setup the pen tool and begin creating paths

Before choosing the pen tool, first create a new layer. The paths will not show up in the layers palette but the stroke that is applied to the paths will be drawn on this layer. Now, choose the pen tool and be sure the "Path" option is selected in the pen tool settings tool bar at the top.

With the pen tool activated, begin drawing the paths. To create the curved paths, click and drag when choosing the points on the path. This will create handles that can be used to control the size and shape of the curve at that point. 

3. Stroke Path

Once you get the path where you want it, right click near the path and choose "Stroke Path". If this option is grayed out, double check that you have the new layer selected that was created in the previous step. 

A second dialogue box will appear asking what tool to use for the stroke. We want the "Brush" tool since this is what we set up in the first step. Then choose "OK". 

To finish the path, hit the enter. Repeat these steps to create each path.

4. Generate many paths at different levels of opacities

I want to create a hierarchy of paths revealing different levels of traffic intensity. This is shown through both a density of lines and levels of opacity. For this image, I created three different path layers. The first layer was set to 100% opacity, the second to 50%, and the third to 15%. 

5. Add line work glow

I want the line work to have more of a presence in the illustration, so a slight glow will be added. This is done simply with the brush tool. I used a soft brush, 90 pixels big, and set the opacity to 12%. Where the lines are dense or converge together, I layered in some black paint. 

I also duplicated the dark paths layer and applied a Gaussian Blur filter. 

I removed the background so that this step could be seen a little more clearly.

6. Add Color

To further punch up the paths, I'm going to add color. To make things easier, first merge all of the path layers together. It may be best to first duplicate these layers and turn off visibility so that you will still have the original individual layers available to edit if needed later on down the road. To merge, select all of the path layers, right-click on one of the layers, and choose "Merge Layers".

Once the layers are merged, right-click on the new single layer and choose "Duplicate Layer". 

With the duplicated layer selected, choose "Image>Adjustments>Hue Saturation" at the top. In the dialogue box, first check the "Colorize" box. Then move the "Lightness" slider to the right to ligten the line work. Also move the "Saturation" slider to the right to increase the color. Finally, adjust the "Hue" slider to the color tone you prefer.

7. Set Layer to Overlay

Finally, set the blend mode of the colorized layer to "Overlay". This will help blend the color into the image and let the darker line work underneath show through. 

The final result is a series of smooth curvy lines created without the need to jump into another program such as Illustrator or CAD.

SITE ANALYSIS DIAGRAMS

I have been experimenting with some site diagrams of the existing conditions of Long Wharf in Boston. I am mostly interested in introducing texture and depth to diagrams that are typically presented in a more simplified manner using solid colors and no gradients. Don't get me wrong, I am a big fan of the "BIG" type diagrams which essentially strip down the graphics to the bare essentials to explain a concept. However, I want to go to the other extreme and see what kind of diagrams can be generated using lots of texture and shading.

Above is a composite image of several different diagrams layered together. Below are the individual diagrams. The goal was to give a slightly different graphical look to each diagram but have the whole series feel as if it came from the same family. These were all generated from one Photoshop file, but with different color overlays and levels of saturation applied to each.

IMAGE BREAKDOWN

The above diagrams are built on a simple base that is made up of two images: a clay model rendering and an aerial image. I like to overlay the aerial image to bring in more information, detail, and texture. However, I lower the opacity quite a bit so that the aerial image isn't too overpowering. In this case, I desaturated the aerial image and will bring in the color later. 

Above: A clay model rendering using Kerkythea. See tutorial HERE

Above, the clay model rendering with the aerial image overlayed. I then lowered the opacity of the overlayed image to about 35%.

With the base image setup, I then began applying color on top of the base image to punch up certain aspects of the illustration such as buildings, roads, and water. Each color overlay is on its own layer (such as the roads on one layer, buildings on another, etc) so that I can individually control the color and opacity. 

The edge of the wharf and buildings need to be better defined, so I applied a "stroke" to the colored layers. This is where having the layers separated out worked to my advantage. For example, I chose the layer that contained the blue color overlay for all of the buildings. I went to "Layer>Layer Style>Stroke" and gave a stroke width of 4 pixels. This placed a black outline around that layer and therefore around each building. I also applied a stroke to the edge of the water, docks, and boats to help define those elements as well. You may also notice that I added a diagonal line hatch to the water and buildings. This was a texture I found online and applied as an layer overlay.

From here, I began adding guidelines, trees, and other elements for diagramming.

Finally, a few more textures were applied along with the pedestrian traffic and boat traffic linework. The pedestrian traffic lines were tricky to put together, but it ended up being a combination of painting the linework in Photoshop as well as dissecting parts of an image that I found online of flight paths. 

I scimmed over many of the details of this illustration. However, as I generate more diagrams for this project, I will narrow in on specific techniques used. For now, I am still experimenting and testing out ideas. More on this later.

ON THE BOARDS

I let a few weeks slip by on this website without a post but it hasn't been for nothing. I have been hard at work on many things behind the scenes, one of them being working with Blurb to re-release Portfolio Vol 3 at a new lower price. I have also been spending time designing and modeling up a project that will give me some new geometry to create illustrations with. This project was chosen to allow me to experiment with certain ideas that I haven't covered in depth in the past. Specifically, I want to look at diagrams and how to generate them quickly and easily. This project is also located in an urban environment. I have worked on a few urban renderings in the past, but this one is a little different and sits on the waterfront. This means more opportunities to experiment with illustrating water, water reflections, and how the architecture meets the water.

The plan for this project is to redesign Long Wharf in Boston, Massachusetts. I visit this area often and it is one of my favorite places to go in the city. It is a busy hub for many of the city's ferries, harbor cruises, and whale watching tours. In the summer months, this area can attract many tourists due to its mix of water traffic, views of the harbor, historical context, and nearby aquarium. I am interested in rethinking the use of this wharf and how people inhabit the many different spaces.  Without getting too deep into the specifics, the complexity of the context offers up many different avenues to explore architectural visualization.

The design is in its final stages but still needs much refinement. I have plans to start with some macro site analysis diagrams but then move into diagramming the design of the wharf itself. The other opportunity with this project is the use of texture and the crucial role texture will play in the proper reading of the design.  Finally, I want to make it a point to be more explorative with graphics therefore expect some not-so-mainstream styles. So, those are my plans, but let me know your thoughts and what you would like to see graphically. If I receive a lot of feedback for a specific type of visualization then I can try to incorporate it into a future post.
