Yes, I need camera help. This little Polaroid just won't take good pictures. I've tried every setting. I am taking it back. I need a decent budget camera that will take good quality pictures that are not huge in memory size. I just need it for taking pictures of product for uploading.
Ok you're going to need a few things, and to get a little more serious. This will ultimately benefit you more than you think I bet, having good photos.
Get a
Canon PowerShot SX530; don't forget to buy a separate memory card. (I would splurge for a
Nikon D3400, but I'm trying to keep it low $) You're going to shoot in Av mode so you can set the aperture high for depth of field. It has selectable resolutions so you can shoot fairly small to decent sized, and you can select file size by adjust the "fineness". You're going to have to put it on a
Tripod. And you need some
lighting.
The Nikon has a higher depth of field. That means you can get more in focus. When you're in aperture mode it will adjust shutter speed automatically, but you want to use the delayed photo taking. It's the feature that makes the camera count a few seconds before taking a photo. That way you aren't jiggling the camera when you take the photo, even though it's on a Tripod.

The lighting is just... you can't do that with flash. It also helps blow out the white background better. I think a long piece of white paper works well. Cheap and easy to replace, as well. Sometimes you can find rolls of it for cheap.
For under $400 you'll be able to take some pretty darn nice photos. Pretty damn cheap!
