Part: III Photoshop Elements > Introducing Photoshop Elements

Chapter 21. Introducing Photoshop Elements

Adobe Photoshop Elements 2 is an amazing digital graphics program. Essentially, it is a program that juggles numbers. Changing the numbers in the computer memory changes what you see on the screen. If you're good enough at math to know which numbers change, and by how much, you could make all those screen changes by hand. Most people aren't. (Besides, it would be terribly inefficient to make all the changes manually.) That's where Elements steps in. Let's say you want to draw a red line about halfway down the page. You could figure out the positions of the pixels to change and change the color of each one from white to red. That's too much work. Let Elements do it. You just pick up a paintbrush, choose some red paint, and draw your line. There it is. The computer has taken all the math out of your hands and done the operation much faster than you could have on your own.

Now let's say you have a photo that's much too dark. If you were a photographer working in a darkroom, you would have to do some experimenting to find out how much lighter to print the photo. You'd probably find out that some parts need to be 15% lighter, some others 30% lighter, and some parts shouldn't change. You'd have to try to find a compromise and would probably waste several sheets of paper trying to get a good print. With Elements, you can look at the screen and lighten the image by moving a slider. More importantly, you can select and lighten specific parts of the picture without changing the rest. You've finally got control!
