I have been doing a bit of macro jewelry photography for a customer of mine (this is my first time tackling this type of photography). I'm using a D80 with mirror lock activated, quantaray 28mm-90mm lens with macro setting locked at 90mm, ISO100, light tent, three 5500K continuous lights and tripod of course with a wired shutter release attachment. My results are very good in my opinion for what I'm being paid, but I'm not achieving the absolutely flawless results I've seen with high exposure professional jewelry photography. If anyone here does this type of work, could you fill me in on some equipment used and other techniques. Thanks.
