Interior photography and architectural photography is an art in itself, the photographer has to have feelings for the architecture and the space created by the designers, there has to be a kind of symbiotic connection.
Usually within the space or room there are POV sweet-spots, that means finding and recognizing certain angles and Points of Views that the designer intentionally created and its important to find good angles that show the important features of the space.
Most designers and architects spend a long time on designing a visual impact at the entrance to the space. The viewer will be presented with a perfect visual balance on entering the room, where lighting looks perfect, room focal points are all obvious and the viewer will have a good feeling when entering the space.
Architects usually design several “sweet-spots” that need to be discovered by the photographer and portrayed in a way that celebrates the space and its talented creators.
Sometimes things are not what they appear to be, interior shots may not be factual and Architectural photographs do not always show what is there, but what is more important is that the photograph shows how the space feels and how the nature of the area is shown.
This isn't so much philosophy as much as strategy to ensure that you have photos to have a philosophy about.
I always straighten the vertical perspective lines to be orthogonal & while the lens typically register angled perspective lines they seldom look good in a finished shot. I bend reality using Photoshop post production to make many corrections that cannot be achieved on site.
Typically a photoshoot that takes one day requires one and a half days of post production. (I include all retouch and corrections in the standard cost of the shoot, FREE)!
