Grey's Anatomy, and Cougar Town, no wonder... Parents watch it, I am really not into that stuff

Thanks O,

That freaks me out...

Color to alpha to remove the background white and a spiral gradient placed beneath.

i stumbled on a engraving script
http://pages.infinit.net/leware/engrave.html

but maybe Ofnuts has something even better boiling...

I wrote a greyscale dithering script a while back that will work with any greyscale dither pattern and convert the image.

here are samples:


And the script is here: http://www.silent9.com/incoming/scripts ... dither.scm

Thanks Rob

The script is grayed out in my list. I have a grayscale pattern beneath the picture I want to dither.

It requires the image to be RGB, so just convert the image mode.

Very similar results to my technique. Do you apply a vertical blur before the threshold?

That worked. Thank you. I've had that script for awhile. I don't remember when I used it before.

That is a interesting kind of pattern

The technique implements this one:

-Rob A>

So, my technique is somewhat different:

Make a 80% grid in one layer (for instance 20 pixels, 16pixels black)
Make a 20% grid in the layer below (20px/4px) center on the "thick" one.
Make a third layer with the image, convert to monochrome, blur it by the size of the grid (20px), an invert the colors.
Make sure that this layer is the only visible and duplicate one of the color channels (they are all the same)
Hide that layer (you can even discard it at that point), make the two grids visible
Add a layer mask to the "thick" layer, and initialize it to the duplicated channel.
Play with brightness/contrast on the layer mask until the images shows up to your liking
Apply the mask
Add white (or whatever) layer below grids
Merge these three layers
Blur vertically by about a quarter of the grid step
Apply threshold.

I saved the pattern with the name, Rob A Dots. I don't know where I got it but I know I used it for something we were doing over in GTalk.

This Op-art is giving me some pretty good ideas!

That was Rob A's version of a hedcut pattern we used to follow his Registry formula:

Oh yes now i remember...i even did a lot of "derivative pattern" from that...

From link to link i traced part of what we did with that pattern...quite cool

I grabbed the pattern thank you all.
