by increasing the lens to film distance the light essentially is weaker which may require you to increase the exposure times or to open up the aperture a bit. When dealing with bellows or extension tubes you have to take into account the "bellows compensation rule". It is something I have to do all the time when I shoot with my view camera and I have my bellows completed extended. http://www.tpub.com/photography1/ph20963.htm

As already stated some macro lenses require an extension tube to produce a 1:1 image.
You might also try extension tubes on a telephoto lens.
If you are really interested in close-up/macro photography, you might enjoy this book: "Adventures In Closeup Photography" by Lief Ericksenn and Els Sincebaugh.

Extension tubes degrade picture quality. But thats not always true, depends on the lens and quality /size of extension tubes.
