Take those blemished, scarred, off-color photos and touch them up like the pro's do (like fashion editors): Photoshop is (unofficially) dermatologist recommended!

Do you ever have any photographs that you would like to restore or touchup? If you can think of it, Photoshop can probably do it! Let's talk a little bit about photo restoration and retouching here.

Touchup is something that is very practical and any proficient PS Designer must understand and many novices will find very useful. After you're done retouching, just output the final image any way you would like (ie. web, print on photo paper..)!

Photoshop is perfect for retouching and image enhancement. The first thing you'll want to do is make sure the image is color corrected and light-balanced. You can just go under Image> Adjustments and bring up the levels command and color balance (if necessary or Match Color).

Maybe try the shadow/highlight tool if you need to bring up darker areas, otherwise with levels you can adjust the lightness, darkness and contrast of the image by moving the sliders.

Remembering that when you go straight to make an adjustment that you are making an adjustment on that entire layer that you are on in the layers palette. You can also make a selection on that layer and apply adjustments only to the selection (ie. an area within a rectangle marquee).

Ask yourself if you are sure you want to go ahead and make adjustments on this original layer. I recommend either doing an adjustment layer (which will appear on top of and apply changes to the layer below) or create a duplicate layer of the original (which you will have to do anyways when you're making changes such as moving or altering pixels (healing brush, etc.)

There are different ways to get things done. But always make sure you make a duplicate of the current layer when you are going to change any pixels. If you know that the layer needs a permanent adjustment changes you can make it right on the original layer and save it like that but it is always safest to keep an original copy as a bottom or background layer.

After you've made basic image enhancements using adjustments, you can use several different tools and filters to further enhance or retouch/restore your image. It just depends what challenge you have. For example you can use the healing brush, clone stamp, patch tool and even the new color replacement tool (in CS).
