HDR, Ambient or Flash Interiors

As you know I am a big fan of HDR landscape photography but I have also been experimenting with it indoors. I took three shots of this condo interior below. This first one is with ambient light only, the second is using a flash with a shoot through umbrella and the third is…. a serious of seven shotes taken at different exposures combined in a composite. Which one do you like the most? I love the way off camera flash brings out the structure, depth and contrast in any image wether it be outside or inside, day or night. I just thought I would share this as I learn and find out how different lighting affects things.

Ambient light only.
