No flash, ambient light. A two-part daily photo - the "fav" is a selected color B&W and the 2nd is the original from which the B&W was derived just to show the comparison http://ed-k-photo.smugmug.com/gallery/6430099_RkaPU#424551700_t3zkW
Both of these images involved more post-processing than is usual for me. The original (color) is a 3-exposure HDR (it was pretty dark in this room and the tonal range from the fire/lights to the dark paneling was about 15 stops - HDR to the rescue). I used Essential HDR (for this image it was better than Photomatix) for the HDR and Nik's Silver Efex Pro for the B&W conversion (used the "Brush" option to erase the B&W over the fire). It may (or not) seem complicated, but it's less than 5 minutes all told.
The 3 HDR exposures were made at -2, 0, & +2 EV, 20mm, f/16,& shutter speeds from 1/8 to 2.5. Oh yeah - tripod. I was especially impressed by the way HDR Essentials preserved the flames in the fire. With one exposure of 2.5 seconds I was expecting more of just an orange blur.
Not my living room - a community club dining room.
