Shrek 2 Stills Retouching

Hank's Photoshop Retouching Tips and Tricks

Do not paint on the original layer. Save it as your base layer.
Create new layers for retouching efforts, create a group for many layers if necessary.
Use the selection and feathering tools to isolate elements.
Name your layers or groups to stay organized.
Most high resolution 3D renderings need work, so do not hesitate to fix with artistic painting.
Use the cloning tool brush, to grab the grain and nuance from the original image.
Take advantage of the "Lighten" and "Darken" brush settings.
Use large, soft brushes at under 10% opacity for subtle erasing, lightening, shading.
Be prepared to use Undo and History for multiple undoing.
Use the Pen Tool when you need to create exact paths and selections.
Of course... use a pressure sensitive painting tablet , such as the Wacom.
