How to build a cheap light tent - update 2

I have replaced my old giant light box with a new smaller sleeker model. I went to Wal-Mart and bought a smaller box and two sheets of poster board. When I got home I cranked out my new light box.

I made a few structural modifications that were recommended to me by the author of He also made a light box a while back but he didn't cut the entire top off of the box. Instead he left a 2" border like on all the rest of the sides. This made the box a ton stronger.

I am pleased with this box. I have taken a few pictures with it and I can tell a pretty big difference.
