Dear fraserstones, Thank you so much for that info, it is really helpful. I had already figured out the part with the kelvin lighting, my 7500k were too blue, I’m pretty happy with my new 5000k. Then I have a set of incandescent, the run on the warm side, about 3500k and then the set of reveal which are somewhere in between. Mostly I use the incandescent lights for the opals and a very low lighting on the camera, almost like a shadow, even though the opals are bright in regular room light, the colors just don’t come across in the photos correctly. Also I have only had luck with a single light source. Thanks for giving me some ideas!
