In photoshop, I want to make the blue colored areas black as the sea level for use in OpenTTD. Easy enough to use magic wand to mask and have a black layer below to get the desired effect.
However, I want to have some sort of gradient applied to the surrounding terrain along the outline of the lakes, in order to get a better transition. Would anyone like to point me in the right direction on a possible method to do this?
