I could swear that I've used a filter about 1-1/2 yrs ago in either Photoshop or Illustrator that gives the image an impressionist effect. You could choose Van Gogh, Renoir, etc. I just asked someone and was told that it was Painter that has that filter, but I haven't used Painter in years. I didn't see anything in KPT, either. I have a wedding photograph that I would like to make look like a painting. Does anyone have any idea where to find a plug-in like this?
Solution: Impressionist Filter
Hmmm. . . . The PhotoShop 4.0 artistic filters offer some good variations on brush stroke, watercolor, paint daubs, etc. You might try fooling around with these.
