The point for a lot of folks to use a tent set up is so they can maximize what they can get out of a point and shoot. Not everyone wants to invest the time or money in a full camera set-up.
These pics were taken with my Sony point and shoot in a Ebay light tent. There is minimal post processing vis Pixelmator on a few.
Don't get me wrong, I plan to buy a nice camera set up for taking other kinds of pics, but if you are just taking pics of your snakes a light box and point and shoot can go a LONG way.
