You don't need a camera to take a screen shot of your computer. In fact, a camera would probably give you an extremely blurry picture! There is a special button on your keyboard called Prnt Scrn. All you need to do is press that button. The screen shot of your desktop is then stored onto your clipboard. To get it off the clipboard, you need to paste it in paint. Open it up, go to edit and click paste. Then go to file and click save as to save your file. Choose where you want it to be saved, name it, and you're done!
