I wanted to create a long tunnel but because I don’t have unlimited space the set was built using a forced perspective. The front is 4 feet wide by 2 feet high and over its 7 foot length it tappers down to 1 foot wide by 6 inches high. The photos hopefully make it clear. All the detailing gets progressively smaller as well to give the illusion of distance. Everything at the front of the set is 75% larger than everything at the end of the set. That includes the scale of the graffiti and the props. It’s very effective but … the trade off is that you can only shoot the set from a limited number of angles. However, I think I’ve constructed the scene in such a way that none of that will matter.
