I posted a landscape video tutorial a few weeks back, however the video did not cover some final post processing steps used for the final look. I received some comments asking for an explanation so I thought I would put something together quickly. The steps are basic and better explanations can be found under the quick tips section of the tutorials page.
At the end of the landscape video tutorial, the image was looking good (Below), however there were a few subtle details that I still wanted to adjust.
1) First, I found an image of people at the correct camera angle. I quickly cut them out by erasing the background with the eraser tool.
2) The cutouts were dragged into the illustration and scaled to the correct size. I also painted in a soft shadow to set them into the image. Another tip is to desaturate the people about 50% so that bright color clothing doesn't become too distracting. It also allows people taken from different images to look better next to one another.
3) Next, a new layer was created filled with an orange color similar to below. I used a soft brush with a low opacity. The color was really saturated over the pond to play up the reflection off of the water.
4) Double check that the orange layer is at the top, and set the blend mode to "Overlay". I like to give my illustrations color overlays because it helps to tie all of the different Photoshopped elements together, especially in an illustration like this with different trees and grasses. A more detailed description of color overlays can be found HERE.
5) Finally, I want to add just a little grunge effect. Find a good grunge texture and move it to the top of the layers pallet. The one I used has an orange hue to it which will strengthen the orange in the previous step which Im fine with. If I wanted, I could desaturate the texture to avoid the added orange color and just utilize the texture.
6) Set the new grunge layer to "Overlay" and lower the opacity. A more detailed explanation of the step can be found HERE.
Ive realized that some of the biggest moves I make with architectural illustrations happen in the last few seconds of postprocessing. The mood can be completely flipped with just a few color overlays. A have saved a lot of weak renderings with these simple steps.
