Things You'll Need
Instructions
Remove the lid of your shoe box. If there are any flaps or other pieces of cardboard attached to the top edges of the box, cut these off with a utility knife.
Cut several pieces of white construction paper large enough to cover the bottom and sides of the inside of the shoe box. Apply the paper to the inside of the box using a glue stick. Let the glue cure for the time suggested on the container before proceeding to the next step.
Turn the box so that its bottom faces upward and position it horizontally. Use a utility knife to cut a rectangular hole slightly smaller than the size of your flash unit's adjustable head in the center of the box. Flip the box back over.
Lay three sheets of white tissue paper over the top of the box. Pull the paper taught and secure it to the outer edges of the box with white masking tape.
Mount the finished light box to your flash unit by inserting the adjustable head into the rectangular hole in the underside of the box.
