A complete and concise guide about screenshots in Mac OS X, and everything you need to know about them.
Let’s begin, shall we?
Full Screenshot: Fairly well known, by pressing Command () + Shift + 3 you will get a full screenshot.
Selective Screenshot: Much less known than the Full Screenshot, by pressing Command () + Shift + 4 your mouse will turn into a sort of cross-hair that will allow you to select the portion of the screen which you would like to capture.
Perfect Selective Screenshot: Barely anyone knows this sucker! Press the same key combination used for a Selective Screenshot, but before selecting the portion you want to capture, press space. Your mouse cursor will turn into a camera and simply mouseover whatever you want (i.e. windows, icons) and it will take the screenshot to the exact pixel!
Taking a screenshot of a webpage: While you can do this with a Selective or Perfect Selective Screenshot, sometimes, the whole webpage is just too big to capture the whole thing in one screenshot. That’s when Paparazzi! comes in. This handy freeware application will take a screenshot of the full webpage, all you have to do is enter the URL of the webpage, and leave the rest to Paparazzi! It also allows you to change the size of the image you want, and has a cropping feature.

Other information concerning screenshots:
Changing the image format: The default image format of screenshots in Mac OS X is PNG. However, you can easily change the format to any other image format with a customization/maintenance application. Might I recommend Onyx?
Get Onyx here.
For those who want to use an application to take screenshots, I recommend SnapNDrag, you can also select the image format you want when taking the screenshot.

Well, that’s everything you need to know about taking screenshots in Mac OS X!
