Have you ever wondered how some people post pictures online where the eyes of the subject just 'pop'? Well, I am going to teach you one way of doing that to your pictures. I work in Adobe CS3, so if you are working with a older or newer version, your screen may look a little different than mine. And there are several different ways of doing this, but this is the quickest way for me :)
First, open the picture in photoshop that you want to work with...
Next, zoom in on the eyes to make it easier to see what you're doing...and click on your 'lasso' tool. trace around the first eye (it doesn't have to be perfect), then while holding down the 'shift' key, lasso the other eye. So now both eyes should have a moving dotted line around them. Now, right click on your mouse and select 'feather'.
and put your radius at 10 and click ok.
Next, go to your 'filter' tab on top of your screen and choose 'sharpen', then 'unsharp mask'
Play around with this a bit until you get the look you want. You can check the box that says preview to see the difference before you ok it.
But be careful you don't over-do it....you can end up with some scary looking eyes!
Here is a picture of the before and after....
