1. Here's a simple trick to create a sketch effect. First, open the image you want to 'sketch'. (Me)
2. If your using Photoshop 7, use a 'Layer Set' for organization.
Next duplicate, the original photo/image layer( I called mine 'copy'), and hide the original.
Select the copy layer, then go to 'Image/Adjustments/Desaturate'.
(Alternately, PC Shortcut: 'Ctrl + Shift + U' = Desaturate | Mac Shortcut:'Cmd + Shift + U' = Desaturate.)
Above is what your 'Layers Palette' would look like, and below is the 'Desaturated' image.
3. Next, duplicate the 'copy' (desaturated) layer.
Select that layer, then go to 'Image/Adjustments/Invert'.
(Alternately, PC Shortcut: 'Ctrl + I' = Invert | Mac Shortcut: 'Cmd + I = Invert)
Above is what your 'Layers Palette' would look like, and below is the 'Inverted' image.
4. Now, Select that 'inverted' layer, in the 'Layers Palette', and from the 'Blending Modes' drop down list, choose 'Color Dodge'.
(Alternately, PC Shortcut: 'Alt + Shift + D' = Color Dodge. Mac Shortcut: 'Option + Shift + D' = Color Dodge.)
Above is what your 'Layers Palette' would look like, and below is the 'Color Dodge' image.
It should be mostly white. (Mine is not, only because I previously cut the background out of the image.)
5. Finally, have the 'Color Dodge' layer selected and go to 'Filter/Blur/Gaussian Blur' and toy with the 'Radius' integer. In this case, a 'radius' from '1-9' worked best. Anything after that it just restored the image back to what it looked like when we desaturated it.
Some enhancements, such as shading and colored eyes. To see how I did the eyes in the below example CONTINUE TUTORIAL HERE.
Works well on all sorts of image types
