    + 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.

    Rob A -

    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.

    Great tut, OldGuy! Thanks for taking the time to write this! It works amazingly well. How do you guys figure this stuff out?! XD

    And, thanks, RobA, for converting it to GIMP!

    I might have went a little wild. XD

    Ok, I know I spent too much time playing video games when I was a kid, but is that the map from Dragon Warrior?

    lol, yeah.

    Here's an old version that I've re-done several times since then:

    This is with the original map at 10% opacity so you can see just how surprisingly close it is to the original:

    Time to start in on the mountains... I'll place them reminiscent of the Nintendo map, without sacrificing too much realism.

    Info Tutorial linked in the Tutorials in PDF Format thread

    Hello, All.

    I've linked the "Creating Realistic Coastlines" tutorial by OldGuy and PDFized by jetmore.

    The link can be found in the Tutorials in PDF Format thread on Page 1 and in the "Photoshop-Related Tutorials" section of Post 2.

    Enjoy.

    Regards,

    Vandy

    Here is what I did with your tutorial and Chucks Photoshop Mapping Tutorial (Just using difference clouds and thresh hold) On the making a realistic coastline, I kept my white land mass layer on top and the black below and then:

    * Filter | Noise | Add Noise (gaussian, monochromatic, set to 100).
    * Filter | Blur |Gaussian Blur (set to 2).
    * Merge the layer onto the black layer
    * Select Magic Wand Tool, click in the black it will give a slight buffer around the area you intend for your land mass.

    Then I inverted and then inverse and used a brush to paint in the inverse selection with white.

    And that comes out to the picture below.



    Its larger just had to use photobucket which resized it.

    Just thought id share this info i stumbled on while using this tutorial.

    Thanks. This was extremely helpful. I was reading about a technique for doing this using cloud filters and I was dreading doing it like that. I set this up as an action in photoshop and now I can rapidly erode the landscape. Doing it a lot makes spiffy little islands along the mainland. Very cool.

    Excellent!

    I had been unsuccessfully experimenting to get something like this working on some scanned map sillouettes, and your guide worked wonders.

    You have my thanks, good sir!

    Ditto.

    I'm using this technique on a current project, and want to add my thanks.

    cheers.
