I am putting my little 1 bdr 600 sq ft house up for sale this Thursday, and have been taking the interior photos myself. After reading about interior photography, and looking at a lot of photos from higher end real estate listings, I have decided that wide angle lenses are distracting and somewhat dishonest, and the HDR technique (merging differently exposed photos in Photoshop, to get a 'High Dynamic Range' of exposure) to get uniform exposure is too weird looking. My suspicion is that when people visit the house, after looking at wide angle HDR images online, they might feel discombobulated by reality.
And so, I am taking two photos using a 35 mm lens and a tripod; one photo exposed for the interior and the other for the view out the window. In Photoshop I tweak the interior photo, add a layer, and paste in the window photo. Then I delete everything from the layer that isn't window.
Plus, I 'staged' the room to look lived in but uncluttered:
One website on interior photography says to, 'shoot from belly level.' This apparently draws the viewer into the room.
Anyway, interior photography is kind of fun.
