I'm using PS CS 2.
Start out with your base, cropped to 100x100. This image is from
Veronica-Mars.Org Duplicate your base and set the duplicated layer to Screen, 100% opacity.
Duplicate your base image again and move the duplicate above the screened layer. Desaturate this layer and set it to Soft Light, 100% opacity.
Merge your layers together so far by creating a new layer and pressing Ctrl+Alt+Shift+E. Then Unsharp Mask (Filters >> Sharpen >> Unsharp Mask) at about 70%.
Create a new layer and place this gradient at Soft Light, 100%.
Create a new layer and place this gradient at Multiply, 60%.
Create a new layer and fill with a creamy bright yellow (#fff799), set at Multiply, 20%.
Create a new layer and place this gradient at Color Burn, 100%.
Create a new layer and place this texture by
noctuidae at Multiply, 100%. Erase the part off of Veronica's face.
