Been away too long and need help possibly due to being 80. Trying to photograph jewelry by a crafter and having some issues with focus, settings and actually taking a photo. Tools I have are a Canon Rebel T3i EOS 600D, 4 lenses: 70-300,55-250,18-55, 50mm compact -macro and 4 close up lenses +1,+2,+4,+10 and a 25x25 photo light box. I have tried full auto, manual, ISO, aperture, shutter speed and no results. Products are all draped on black silhouettes. Need help.
