I wanted to do an eye tutorial. So, here are steps I take.
Let us start with our original image. I cropped it close since all we are doing are eyes and the details may be seen.
I usually start with lightening the color part of the eye. Sometimes this is a bad thing to do, but for the tutorial I will include it.
Next I make a darker ring on the outside of the colored part. Models who natually have this are great. If they do not you can make a slight one by burning one in or drawing it on another layer. Do it as you will. No 'right' way.
Another step is to darken that eye shadow. You don't have too, but I think it looks nice.
All I did here was cleaned up the white part of the eyes.
Here I used the Unsharpen filter only on the eyes. Sharpening eyes makes them pop. Sometimes it makes them look really bad if oversharpened. (which I think they are a bit over done here, sorry, but i already uploaded the image and do't want to re-do it haha!)
The before and after.
Any questions, post or PM me. And, if you read this and use it, at LEAST leave a comment that you had.
