So I wanna make an inexpensive light box so that my photos'll look somewhat more professional. Question is, how will I go abouts building one? I have a box that's about the perfect size picked out, but what other materials might I need?

and one additional thing is to place a curved piece white posterboard as your background, so you don't have a "horizon line".

 

well butter my biscuit. i didn't know that about a horizon line.
learn something new each day.

 

and knowing is half the battle.
