If you need to take a picture of something small, with a neutral background, you can easily make a mini home studio with a piece of white typing paper and a spot of tape. Just tape the paper down at the front and curve it up in the back. Simple!

The results:

Canon 40D, Tamron 18-270 at 70mm, Aperture Priority at f/10, 1/25, ISO 800, natural sunlight
