Light tent, or Light box is a piece of lighting gear used mostly for product shots. It creates a nice, smooth, safe light with almost no hot spots.
We've posted a tutorial for a really simple light box before. This light box was made of a simple cardboard box and was super easy to construct and really dispensable.
Reader Randi Scott constructed a PVC light box skeleton that is both sturdy and, not dispensable, but can be stowed away so your significant other will not complain. Read all about it and learn how to make one yourself on this link.
