@TomB asked in the tree thread that I post a pic of my light box setup, figured this was a more appropriate place for it, so here are a few shots of listings in eBay here you can buy one just like the one I got... it is fairly cheap, I am sure there are better products out there if you need something professional!
The actual one I bought was a couple bucks cheaper and had a phone tripod included:
The goal is just to get a completely white (or black, blue, red...) background that fades from the vertical to horizontal which creates the look almost like the tree/ object is floating, completely removing the focus from your background and onto your subject. There are other ways to achieve this look, the light box is limited by it's size, but they make them as large as 5 foot cubes from what I have seen. I found the lights included to be below average but I have already got multiple studio and clip lights from my attempts in the past to boost my lighting so I added a few to the mix here as well.
