Colorizing Images

1) New Document, Find some eye or lips or anything you would like to colorize.

2) Grab the Lasso Tool (L) and make
the circle over the image
remember to get both eyes
together after you finish
making the circle around the first eye press shift and trace the other eye
that way you wont loose the first selection.
3) After you got both eyes copy/paste the eyes into another layer go to
Image --> Adjustments --> Hue/Saturation and colorize them any color you like, apply.
4) Then go back to the eyes layer and just earse the borders of it till you get them done perfectly. Thats it :)
5) Duplicate the layer and give it
a Color Dodge layer effect :)
