How to Make Your Own Light Box - Construction
1. Reinforce the flaps in the bottom of the box with tape inside and outside.
2. Turn the box so the open end faces you.
3. Cut big windows out of two sides of the box. Leave at least an inch of cardboard on each edge to maintain the integrity of the box.
4. Cut a smaller window (about 6 inches square) in the top of the box, but be careful to leave the bottom edge of this cardboard open but attached. Just score it from the inside, leaving a couple layers of paper attached. If you are using a utility knife, cut the open edges at an angle to keep the flap from falling into the box.
5. Carefully tape tissue over the inside of the side windows. For a sturdier, longer-lasting light box, use lightweight translucent fabric.
6. Slide in your poster board so it curves to cover the back and bottom of the light box.
The board provides a clean background for photos and the tissue paper will evenly diffuse the light. The top flap can be opened to shoot an overhead photo or adjust the light in the box.
There’s your basic light box. Now it’s time to experiment with lights and colors. You can probably angle a basic lamp toward the side of the box and get good, basic product photos. If you want to get fancy, you can use colored poster board. Maybe pastel pink for your doll collection or black for your Metallica bobble heads.
Thanks to the Strobist for the basic outline of these instructions on how to make a light box. His light box is a little less flexible than this one, but he has some other good photo tips on his site.
Finally, your new light box can also double as a marionette stage if you want to get really creative. Just operate the strings from the hole in the top of the box and shine in your light to illuminate your production.
