I've been meaning to buy/build a tent to take better photos of the parts I make and work on. After talking to a friend that shoots photos for a while he sent me a few links with photos of some home built tents so I took a box and paper from work, picked up a sheet from WalMart and used a clamp light I've had sitting in the garage. I have a total of $11 into this thing including the clamp light.
I'm taking the photos with my phone (Nexus S).
The box is around 24"x24"x20".
I first cut out the top and the front, leaving around 2"-3" around the edges.
Then cut the paper to fit.
Once the paper was cut I cut windows in the sides. Also leaving 2"-3" around the edges.
After I cut out the box I wrapped it with a white sheet. The front of the sheet can drop down to cover the front door.
Then cut a slit thru both the sheet and the box to attach the clamp light.
