Border effects can be a very effective finishing treatment for a painting or other artistic visual effect. You can configure the paint synthesizer to create a wide variety of different border effects (check out the Borders category for some examples). But you can also use different image processing effects to provide different aesthetic treatments to the borders of painted canvases.
PLEASE NOTE: You can find border presets in Image Ops > Frames and Borders and in the Paint Synthesizer > AutoPaint > Borders and Frames
The 2 images above show a painted canvas with an image processing border treatment (first gallery image) and the original painted canvas (second gallery image). The particular image operation effect I used for my border treatment was the Adaptive Convex Hull ip op.
This image operation effect includes a Border option for the Modulation parameter. Turning this on modulates the effect so it’s strongest at the borders of the canvas and decreases in strength as you move to the center of the canvas.
You don’t want the Size to be to big when doing this kind of border processing or you’ll affect the center of the image too much. You can play with the Size, Angle Offset, Symmetry, and Algorithm to produce different kinds of border treatments. Running several iterations where you switch back and forth between Max Hull and Min Hull Algorithms can also be effective.
The image operation preset used for today’s effect is available 7811.ipop
You can also check out the Adaptive Filter image operation for this kind of treatment, since it also has a Border Modulation option.
