Last wednesday I visited some friends who own a magnificent apartment in Rotterdam which I wanted to photograph for some time. Often interiors are shot with an extreme wideangle (like 14 mm, which I used when I started) or a nice wideangle tilt-shift lens (17 mm TS-E or 24 mm TS-E). Pros: you can include a lot in one photograph and spaces seem larger. Cons: wideangle use is very obvious and, in my opinion, unnatural. I like to photograph interiors with a 35 mm (like I did here) or a 45 mm TS-E. It looks more pleasant. The drawback is that you cannot get everything in your photograph. I would have liked to remove a wall at the back of the house but that was a supporting wall. And besides, removing it would have resulted in a rather drafty situation.
