I use a light box (home made), special lights and a tripod when I take my photos. My current background choice is pale grey cloth. While fine for my online store and wholesale catalog, I need to step things up for juried show applications. To take my photos to the next level I have plans that include investing in a more professional light box and a gradient background. In the meantime, a friend helped me do some after the fact photo magic with photoshop. Here are the befores and afters.
Owyhee jasper before.
After a gradient background was added.
Glass garden bracelet before.
After removal of the sand dollar underneath and addition of a gradient background.
Snakeskin jasper before.
After some serious tweaking.
Earrings before.
After addition of a gradient background.
