Interior photography, especially residential real estate, is best shot wtih a digital DSLR camera and WIDE angle lenses. DUH!!!
Well, it took me some time to figure out that using the best equipment gives you the best results. After 2000+ homes, I understand the idea of "Don't do it at all unless you do it right."
I use a Nikon DSLR with a 12-24mm WIDE ANGLE LENSE, along with multiple on and off camera flashes when needed.
The great thing about it, I am in and out of most homes in 1 to 2 hours. Every photo is emailed to you within 24 hours and you receive a Virtual Tour Link that can be placed in MLS.
Every listing needs photos, make them GREAT!
