The folks at <a href="http://www.webmonkey.com/tutorial/Lightroom_Tutorial_Overview">Webmonkey offer a free tutorial</a> to help you make the leap to shooting in Camera RAW. The uncompressed RAW image format allows far more control over your finished product than the standard JPEG. With RAW, you can adjust the exposure, change the balance, alter contrast, and make dozens of other tweaks you can't with JPEG files.
