Clear, well-lit photos of your projects are among the best ways to share your work with others. Few techniques highlight your project as well as an all white light box with soft, even, shadow-free lighting. Not only is the white background distraction free, it will also serve to bounce your light source onto your object from nearly all angles.

This is an effective, inexpensive, and easy way to build a light box for project and product photography. Plus, you can quickly break it down for flat storage, and set it back up in seconds!


  • 1 ea. 30" x 20 " x 1/2" thick foam core board (for the floor piece)
  • 1 ea. 30" x 20" x 1/4" thick foam core board (for the back wall)
  • 2 ea. 24" x 18" x 1/4" thick tri-fold foam core board (for the side walls)
  • 18 ea. small magnets, such as these
  • 24 ea. 5/8" wooden cubes such as these 
  • Hot glue gun
  • Blue tape or spring clamps to hold work while glueing


You'll use the wooden blocks and magnets to secure the foam core boards to each other, while still allowing them to be taken apart.

Start by gluing two cubes each on the two back corners of the floor piece, and one cube in the middle of the back edge.

You'll then glue a magnet onto each cube, as seen in the pictures and diagrams.

Three of the magnets face upwards to connect with the back wall, while two of them face toward the front edge to connect with the side walls.

Next, place the back wall up against the cubes, then glue three cubes to the back wall that contact three of the floor cubes as shown. Add the three matching magnets so that they connect to the floor magnets, then glue them into place.

Glue four more cube onto the back wall. Two on each side, each 9" and 18" up from the bottom, respectively. These measurements are approximate. Then, glue magnets facing toward the front edge as seen here. These will be used to connect the side walls.

Once the glue has cooled sufficiently, you can try out the super fun click-into-place action of the magnets!

Now you can prep the side walls. Glue into place three cube/magnet sets per side to align and connect with the corresponding sets on the back wall and floor.

For some extra stability, glue on two cubes at the bottom edge corners of the middle fold panel of each side wall, as well as one cube at the bottom corner of the fold that is at the front wall of the light box.

Use It

Your light box is complete! You can adjust the side walls and front opening by folding the side wall panels. Then, place a large, diffuse light source at the top of the box. I'm using an LED softbox light, but you can get a similar effect by draping  a white piece of shower curtain liner fabric over the top of the box to diffuse a couple of bright lights.

Collapse It

When you're finished, you can pull off the walls from the floor with a gentle tug on the magnets, and pack everything up nice and flat to store for your next shoot!
