How to assemble a photographic lamp is a soft light box.

1. Draw a 45-degree mark on the prepared carton lid with a ruler.

2. Drill a hole from any corner with scissors, then carefully cut off the excess part of the lid along the line and cut the carton diagonally at 45 degrees. After cutting, pay attention to trimming the raw edges of the carton.

3. Stick butter paper in the carton with a glue stick, and stick butter paper from the inside of the lid with a glue stick. Note that the paper must be smooth without dents and creases, otherwise it will affect the light emitted.

Cover the side of the box with a layer of butter paper.

Just put the desk lamp on the back of the carton.
