I needed to photograph some things to sell online, and unfortunately, I have a mediocre point-and-shoot camera, and nothing as far as equipment gos. This is the lightbox I came up with.
Step 1: Materials/Design
I used a sheet wrapped around a metal file rack from inside of my filing cabinet. I had a portable shop light that I held/hung above it, and I put a round cleaner container underneath the sheet to set the items on.
I've heard of people using semi-transparent trashcans, wax paper, and a number of other things as well.
