Thanks : )
Thanks : )
This is very good information.
The tip about starting with a smaller image to get more bang out of adding the noise and then scaling up worked very well for me.
And, because I can't leave well enough alone, I turned this tutorial into a PDF and added some screenshots for the interim steps and dialog boxes. (I like having these handy when I'm between WiFi hotspots...) All credit for the original process belongs to OldGuy.

Thanks for making the pdf. I was too lazy to create the step by step screenshots but I think they help explain the process. One change though. Instead of reducing the image resolution, adding the noise, and then increasing the resolution back (which could lose some detail), You might try creating a second drawing at the reduced resolution, applying noise to that, increasing the resolution and then cutting and pasting that layer from the second drawing into the first. That should accomplish the same effect without sacrificing any detail in the original.
I haven't tried this in Gimp but it should port over. Also, I believe Gimp has the ability to scale the noise directly.
Glad you like the technique. Thanks again for the pdf!

Don't forget to rate the tutorial so it can get the award it so richly deserves! ten 5 star ratings (I think) is what is needed.
PS. good to see you still about Still Cypher (I need to incorporate your amendments into the City Design tutorial)....haven't forgotten!
Here here... I second that! <grin>Originally Posted by ravells
Very cool technique! I've been trying to figure out how to do that. Everything else I've tried ate away at the original too much.
Congrats OldGuy!
The people have spoken, the member have rated, and this is now an award winning tutorial!
