Lately, most of the people use large monitor as their desktop. If you have monitor size of 1680×1050 pixels then if you print screen the entire screen, the file size will be much larger than after adjusting.
If you clever enough, you will make use your photoshop and shrink the file dimension. Therefore, if you want to print five screens then you have to repeat that five times. That will be troublesome, I think.
The easiest way is by adjusting your screen resolution inside Display Preference Pane. Using QuickSilver search for playpref and you will got application you want. Or you can go under System Preference.

For most of people, image take a very good part in creating mood. Sometimes, someone want to take some screen shots from some images to use into some purposes (and I think I use some words that you spell it some).
Mac supplies you with the feature to taking screen shot, that its smoothness is the best. You can capture screen shots into the form of file or you can capture into clipboard for making further modification to your print screen.
I think you all know how to use this print screen thing works. Therefore, I will just give you some tricks of screen shot making.
Do you realize that, Mac uses Command-Option-3, Command-Option-4, Command-Option-Shift-3 and Command-Option-Shift-4 for screen shot taking? Those are very long keystrokes.
For people who often use this screen shot. I suggest you customize your shortcut. You just need to go to QuickSilver and use keyword keymouse and then customize your screen shot shortcut. For your reference, I only customize shortcut for save picture of screen as file to F13. You see, just one key, we can take picture of the entire desktop.
