Script-Fu Charcoal-Layer-FX v1.0 by Micomicon March 2011
A Gimp script which takes the effect from my Charcoal script and adds it as a layer or layers. NB. Does not require charcoal.scm to be installed.
Opening the Layers Dialog and scrolling through the layer modes afterwards can produce some interesting results akin to adding a watercolour wash, the strength of which can be varied by adjusting the opacity slider.
Thanks to mahvin for this change of direction.
To install (Linux):
Download and move the script file charcoal-layer-FX.scm to /yourhome/.gimp-2.x/scripts.
A Gimp script which turns a photograph into a black and white image which can look quite like a charcoal drawing. Works with RGB, Indexed and Greyscale images.
Results can be variable and are dictated by the tonal values of the photo used. Although small adjustments can cause quite large differences, the default settings should provide a reasonable starting point but do be prepared to experiment.
