I often walk past artists painting/airbrushing photorealistic billboards on the sides of buildings. Talent aside, how do they do this? I would imagine that an original image would be projected onto the building, and then traced, but how do they avoid image distortion if the environment doesn't allow for a perfect straight-on projection? Do they project an already-distorted original onto the wall?
