[Award Winner] Creating Realistic Coastlines

[asdel]

Works well in Gimp, too! Very nice technique. Duly repped!

Translated to gimp steps I used were:
* Filter | Noise | HSV Noise (Holdness 1, Hue 0, Sat 0, Value 255).
+ Edit | Fade (Darken Only)
* Filter | Blur |Gaussian Blur (2 or adjust to taste). *(1 will create very fine distressing and the larger the blur, the larger the effect)
* Colours | Threshold (adjust to taste). *(I found 160 is a good start, up to 185 for a lacier coastline)
* Fuzzy Select Tool (Threshold 0), click in black surrounding area.
* Ctrl-I to invert the selection
* Fill with White.

This is a simpler version.

* Edit | Noise | Pick (50/50)
* Edit | Blur | Gaussian (2 or so)
* Threshhold (128, but play with this a lot.)

this will add and remove from the coast line, rather than simply add to it. It maybe works better on simple shapes.
