1. get your good quality image and crop/resize
2. adjustment layer: curves @ input 100 & output 123 ??? apparently....
3. adjustment layer: brightness/contrast both at +10 (adjust either to 0 if it's already bright/heavily contrasted)
3. adjustment layer: selective color (depending on the person's skin tone, i typically play with reds, yellows, and whites) set the neutrals: black to -10
4. merge!
~ i use a photoshop action here so this is roughly what happens in the automation process ~
5. duplicate layer: set to sharpen
6. duplicate layer: set to wayne gaussian blur 4.0 like a madman & blending change to darken & set transparency to 30% to regain social capital
7. adjustment layer: levels -- for these icons i typically set her to 30 / 1.20 / 240 as it gives a contrasted, shadowed look. but this will be much like the selective color layer where it kinda depends on the person's skin tone and what you've already done previously.
8. enjoy your masterpiece
9. masturbate under the moonlight
10. pass it forward when someone asks you sugar sugar how you got so fly
