Cell phones now have a 2048X1152 (2.4 MP) setting which is adequate for images to be posted on forums. Use a tripod or rest to steady the camera. If using a digital camera, be sure to set it on "Macro" mode.

Even in the winter (here) direct sun gives too much glare, but the sun behind thin clouds works OK.
I use a dark grey
solid background 10-12 inches
