I'm investigating ways to make at least "semi-artistic looking" photo frames. All GIMP examples I could find have a "designed by an engineer" look. But if I allow PhotoShop, one can find some quite striking examples; e.g., see

http://www.roge.ru/?page_id=151 "Ragged edges, fuzzy, photo frames"

Essentially, their recipes start the same as GIMP ones, making a complement-to-a-rectangle selection. But then what they do is application of one (or several) of PhotoShop filters. E.g., one of the frames is done with

Example filter chain: 1) GRAIN: 100 / 100 / Regular
2) MOSAIC TILES: 2 / 15 / 10
3) WATER PAPER: 50 / 87 / 89
4) DRY BRUSH: 10 / 10 / 2

Well, I could not find any GIMP filter chain which is kinda similar to these PhotoShop examples. Anyone knowing how to reproduce these PhotoShop filters in GIMP (possibly using G'MIC and/or MathMap)?

Thanks, Ilya

P.S. ========================== Here are some GIMP workflows I could invent

(Start with "a rect-frame" selection.

Light/GlassTile (20/20; or in 2 steps with different sizes) Distort/Whirl 60deg, -0.25
Noise/Slur 50x4 (or Spread)

Then:

Artistic/Gimpressionist/Cubism (The workflow for tries is: Apply/Update cycle, then OK)

OR

Artistic/Oilify 11 Artistic/Photocopy
(I get better results by applying Invert before+after Photocopy)
