If you've entertained the idea of setting up a photo both for fun or profit, this tutorial will show you how to build an ultra-portable photo booth out of PVC pipes and cloth.
Instructables user Dohjoe wanted to set up a photo booth at his wedding in place of a guest book. Rental costs were astronomical, however, so he decided to build a DIY version. He used PVC pipes, fabric panels for walls, his DSLR, a Windows laptop, and even found a back-lit 4" red arcade button on eBay and wired it to to the laptop for easy one-click operation for the wedding guests. The best part is the whole thing breaks down, thanks to the modular PVC design, to fit into a large duffel bag.
Check out the guide at the link below for tips, tricks, and some interesting notes on what he would do differently if he were designing it from scratch again.
