Fantastic tutorial.
I'm following along with the Gimp and am having trouble with 1.4 of the Aged Paper tutorial.
I can't seem to get my rivers to come out nice. They don't fade out like the examples do and I suspect it's because (since I'm using Gimp and it's my first time) I'm not selecting the alpha channel correctly.
Anyone have any advice on how to get that to work with Gimp?
try drawing the rivers in a .5 scaled paintbrush or pencil, and when you do the stroke selection, set the size of the stroke to .1. Ill keep experimenting and ill tell you if i find a better way to do itOriginally Posted by jgerman
What, specifically, do you mean by "fade out"? Tapering? Or something else?

On the tutorial for aged paper (http://www.jezelf.co.uk/tutorials_map02.htm) the first few instructions are related to creating a new alpha layer (or channel, I'm not sure which).
Instruction 1.2 and 1.3 are where the magic (well it's magic to me at least) happens. The creation of a 'Selection Set' from the map alpha followed by the 1 pixel stroke in 1.3.
What I think is happening is that when the stroke is performed, since the selection is from the alpha channel the opacity of the stroked lines will match those of the lines I take the selection from. But I don't seem to be getting that effect.
Looking at the map under 1.4 you'll see that the rivers fade into the tan as the move inland. This is what I assume the effect I'm botching would cause. What happens on my maps is those pieces I erased away in the first tutorial (to get the tapering rivers) don't appear at all and I just get solid lines for the rest of the river.
I may be screwing up a step in the first tutorial (Creating an Alpha Map). Specifically the paragraph that includes the sentence "partly delete away the harder, brighter inner rivers". I'm noob enough to just not know.
I apologize for the round about way I'm describing things, this is all new to me.
