Small spaces are difficult to photograph because there’s no room to move and it’s hard if not impossible to see everything in one shot because most people don’t have super wide angle lenses like professional architectural photographers do. When I’m faced with this challenge I will shoot multiple views of the space, however many is needed to show the critical design elements. There’s no reason to restrict yourself to a single shot of a space.
Go ahead and shoot five or six views, but then select the two or at most three that show your design the best. There’s really nothing worse than showing two dozen views of the same vanity in a presentation. It’s boring and shows a lack of clarity of vision and these days people are paying for our creative vision more than anything else.
