People always ask me what kind of camera do you use? I always tell them it's not so much the camera or the lens but it's actually the lighting. Here are some examples of this same watch with different lighting. As you can see the one with natural daylight is completely lifeless and drab. The 2nd set was taken with a flash. This is taken with the same camera and lens btw. Isn't it amazing how a simple flash can transform the subject? To make this a fish post, I dipped the watch in my fishtank prior to taking the pic
