Wow...I don't think there is a better argument for taking pictures outside, in natural light!
The color and detail are so obvious in this photo and would never have been so true inside...even with my light box.
Now that the weather should be getting better - grab some props, your camera and your creations and head outside.
It can make taking clear, detailed jewelry photos so much easier...especially with natural stones that might show reflections of artificial lights.
I know...lugging your stuff can be a pain...so plan to do several pieces in each shoot.
I am no photo expert but try not to photograph in direct sunlight...a sunny day with a little shade is great...and always use a tripod.
