&CHECK OUT MY OTHER EYE TUTORIAL: [link]
I was feeling like making a tutorial.
Note: this is meant for GIMP but i'm pretty sure it's fine with photoshop also.
I think editing eyes is so cool, don't you?
Image used is from this account, Eye Stock II
Brushes from ~KeReN-R Stars Brushes
Lol, i just reread it and there are some stupid mistakes (like 'bruses' ), just ignore them And sorry for not explaining how to turn image to black and white. Just go to colors->desaturate and choose any of the options and click the button "desaturate".
