I chose the atmosphere "Tel Aviv" in the browser.
I just changed the color of the clouds and slightly modified the position of the sun.
This atmosphere creates an cartoonish atmosphere with sufficient aerial perspective to strengthen the depth of the image.
For the objects: all textures have been modified, as well as colors to best suit the cartoon effect.
Luminescence has been enabled for some materials such as neon and signs.
The overall reflectivity is also enabled for many buildings and vehicles to create consistency in color. (between 10 and 40% depending on the materials).
Many objects are illuminated independently to highlight them.
Different images are calculated with different cameras and then are assembled in photoshop.
Sometimes I had to hide some elements that appeared twice on different images (often distant buildings).
I also had to make the proper connections for the roads, buildings ...
Once finished, the image is resampled for large printing.
I'm also adding a second image I made for this project:
We hope you enjoyed the read. Now it's your time to experiment:)
