Che guevara question

Hi,

I deleted the mail with eth Che Guevara question too hastily, so here's a reply as a new thread.

The problem with doing a threshold on a photo is that you typically get lots of graininess around the threshold borders. If you do a small blur, say 2 or 3 pixels radius, it makes the threshold boundaries much cleaner. You can hand-select parts of the image (such as the star on Che's cap, for example) and invert the selection so that the blur doesn't apply to bits that you would like to stay angular and well defined.

Cheers, Dave.
