I came across by chance some "photo booth" setups that come with a tent-like chamber with lighting and camera positioning mechanisms on Amazon. I'm wondering if anyone uses this sort of thing, as I really did not know they existed until today.
I personally use the sunlight coming through a window and various textures, like a solid colored blanket or a grainy table, and while I think I get some great results, I guess you could say I'm open to suggestions in the photography department. I use a sort of hybrid between a point-and-shoot and a DSLR camera, and usually hold it with my own hands instead of using a tripod.
Here's an example of it when conditions are nice and sunny:

So what are your photography setups? Any advice in regard to buying any extra equipment to aid in the search for the perfect picture? Example pictures welcome, too!
