    Tutorial Making Not So Random Coastlines in GIMP

    After making a couple of random coastlines over here I wanted to make some less random coastlines. More specifically, I wanted to create random coasts in GIMP (or photoshop) based on a rough sketch of a coast.

    I recalled a few tutorials on making lightning using noise and difference layers and figured I'd apply the technique here.

    So what follows is a graphical tutorial on making "not-so-random" coastlines...

    Changing the blur amount or the rendered cloud detail changes the effect.

    It can also be used on any original shape!

    Hope this was useful,

    COOL!! That is a really neat trick. I had done the "difference cloud" lightning thing before, but never considered using it this way. Well done! You deserve some rep, and thankfully I was able to give you some.

    Brilliant! I always wondered what one could use the difference blend for, now I know!
