Help with Swamps

[redleg7]

definitely feather out the edges of your swamp layer where it meets the ground layer. In addition to feathering I would go in with a small hard brush eraser at about 20% opacity and cut into the edges in places to rough it up some.
This gets a more realistic look or artsy look but you will lose some clear delineation of "now you are entering the swamp" it would be more gradual and broken up. So it depends on how you want your map to read.

Thanks will give it a try.

I definitely want it to blend in some.

Hmm, stupid question.

How do I apply feathering?

Here's what I'm doing:

1. Control click on my swamp layer which selects all my swamp shapes.
2. Goto Select -> Modify-> Feather.
3. Enter a value for example 10.
4. Click ok on the feather dialog.
5. The selections change in response to the feather value I entered.
6. Now what? How do I actually apply it.
