I've been tasked with improving our product catalog. Along with clothing, luggage and leather goods, we have a lot of jewelry in silver & gold. Some brass & bronze too. My main concern is trying to match the colors of the gold and silver which can have different polished finishes and slightly different hues and we have a lot of pieces. Are there any tips that may help in pre or post production to match the color of a lot of jewelry? I have some CS4 skills but I've not mastered it. I've been using Camera Raw which seems to offer the most control with ease of use. I couldn't find anything specific to this in my search. I'm using a D90/D300 (depending on what's available @ the time), softbox, two TD5 Spiderlites (overkill but I use them for clothing too), AF-S Micro Nikkor 105mm 1:2.8G ED.
