Hey Vapymid, I like your photos. Please what is your equipment? :) One camera, or two synchronized? And what type of camera? Can you give me a message on Domingster@hotmail.cz? I would appreciate it so much. :)
Roughly, 50cm or so. Regarding the window - I think it's OK in a shot like this. The central tree can pop out a bit and most of other objects around the rim of the picture are more recessed. Another reason for it is to reduce anaglyph ghosting around the high rise buildings framed by the blue sky, so I had to bring them closer to the window, which meant to let the tree pop out.
