I am a metal artist but I make a lot of Jewelry, in fact that is what I gave been concentrating on for the past 5 years.
Taking photos of art and especially Jewelry in such a way that they are shown in the best light and all the detailing & hard work that goes into it are clearly visible is not an easy job. Jewelry usually has subtle textures, precious or semiprecious stones, intricate enamel work or some delicate wire work. Each of these details need to be clearly visible, this usually means having plenty of light, clean backgrounds & a whole bunch of props. These can range from blue tack to hold the piece of Jewelry up without being visible, to various textured papers, to third hands, fabrics and the list goes on.
Of course it goes without saying, you need a good digital camera like an SLR and a nice lens. Now I am no expert and this not a "how to take pictures " blog post so I am not going to get into details about cameras & lenses.
Apart from the equipment I mentioned above I also have props that I put together out of the most unlikely of objects.
For example I use this cut out portion of a paper roll to hold up my bracelets.
Now I mentioned third hand and I do have one that I use both when I am soldering and when I need to hold up a background or support my Jewelry in some way. Besides this one I also have one that I fashioned myself out of some wood scrap, an old brush handle & a clothes pin.
