The difference between plastic black box and octagonal light box

The plastic camera box is a closed space, and the octagonal lamp holder box is an open space, where large objects can be put in and photographed with the help of the octagonal lamp holder.

Adhesive black box is a box used to test the reflection and transmission of light, which consists of a box with adhesive surface. External light can pass through the adhesive surface and be reflected or transmitted by the object, thus testing the reflection and transmission performance of the object.
