A brush metal Leica M3
For this shot I had to bust out the best. I could do. I used a white bathroom tile to reflect back a bit of the M3. A soft box directly behind the camera. 1 flash overhead just in front of the camera pointing directly down to give only a partial reflection (there was a bit more reflection than the photo lets on, but that's what photoshop is for). The ring on the lens is from a DYI project ring flash (powered by a 430EX). And the last light in the photo is off to the left just bare flash directly at the camera to give it some shine.
And then I shoot it as close to camera level as I could without cutting off the ring.
