Im trying to take pictures of merchandise and it needs to have a pure white background. No shadows, no shapes, it needs to look like its already been whited out in the background without actually having to erase around the edges of the merchandise. The color of the merchandise must be as close to the actual piece as possible. Please help!
Not sure how they do it cameras but with video you'd green screen.
You need one solid color for your background commonly green or blue, these colors would have RGB values of pure blue or green. The key is having enough lights so you don't have any shadows on the green or blue so the color is consistent. Once you take the picture in a image editor using the magic wand you can select the color for removal.
I got a long piece of white paper from an art supply store (they cut it off of a roll), taped two corners to a wall, then draped the other end over a small table and place the item on the table. Then I put my camera on a tripod, set the shutter speed to be fairly slow (1/10 to 1 second or so), set the timer, and when they shutter goes off I manually flash an old Canon flash I have at the white paper, behind the item. It's not perfect but it works very well for only costing about 50 cents.

You could also get a slave trigger for under $10. Just screw the second flash into it, and then when your first flash goes off, the second flash will be automatically triggered. So much easier, and cheap!

Wow, I didn't know anything like this existed that was actually cheap. I don't normally use the on-camera flash though, but I could if I rigged up something to diffuse the light from it.

It doesn't have to be on-camera flash - any strobe will trigger it!
But, if you want to use your regular flash, and get some directional light? And do it cheap? Get a cord so that you can get your main flash off the camera - even a short cord will make a BIG difference. Then get a second slave flash going, and you'll have a very cheap two-light system, that will give you directional light. Much better in most cases, than just straight on-camera flash!
I may own a couple of traditional lights, but I really like the idea of using whatever you have on hand. Why go buy more equipment, if you just want to experiment? Use what you have, and wait to buy, until you know what you really want! And, as an added bonus, if you figure out how to get the most of your little strobes, that can be very handy at events, or when you're out in the field, and you suddenly need some light. Experimenting with this stuff is smart! You never know when it might be helpful later.
