Fun With Filters

I just clicked "Filter" then "Filter Gallery" and played around with all the different filters. Some used in this image were:
Artistic -
Poster Edges
Rough Pastels

Brush Strokes -
Angled Strokes
Dark Strokes
Ink Outlines

Distort -
Diffuse Glow

Sketch -
Halftone Pattern

I also played around with various advanced features using the slide-rules to the right. Such as:
Edge Thickness/Intensity
Posterization
Stroke Length/Detail
Texture
Scaling
Relief
Light
Direction Balance
Sharpness
Black/White/Dark/Light Intensity
Graininess
Glow/Clear Amount
Size
Contrast
Pattern Type
etc.
