Hello, I'm relatively new to taking jewellery photos and would like some help. I have a Nikon D100, a 60mm f/2.8 micro lens, and a lightbox to take pictures of rings and other jewellery items. I'm having trouble getting clean, and clear detail of the diamonds of the rings (i.e. seeing the facets and cuts). I know lighting is critical for jewellery shots, but this simple lightbox is all I have. I'm using the highest aperature setting to get the most dof, and a shutter speed of about 1/30s. Is there anything I can do to get better pictures? Any help would be appreciated. Thanks! Cheers, Tk.
