I tried to imitate this effect in Illustrator using scatter brush but didn't achieve it. Does anyone know how to do this? Thank you!
A ten months old case, lifted on the top by the system. User @Theribos has already noticed that this is a mirrored pattern. We use it in Photoshop. There the job is easier.
Because the result is strictly black & white, it's easily traced to vector domain in Illustrator, if needed.
First have a white background. Make onto it the upper half or more and mirror it. The actual drawing is done with using different black scatter brushes. Some greyness and apparent blurriness do not harm.
Apply Gaussian Blur
If you want some small dots stay surely well visible, you can paint them more. Do not blur them:
Goto Image > Adjustments > Treshold to create the blocky BW image:
Do the mirroring. One way to do it is copying, pasting and flipping manually:
- decide where you want the mirror line to be
- take the rectangular selection tool, select the upper half area
- copy and paste it in place; a new layer is generated automatically
- drag the selection upside down in the new layer. Or goto Edit > Transform > Flip vertically and drag the result to its place.
That pattern is symmetrical across a horizontal centerline. And looking to the left, where the dots become individually visible, I find them to be very regular. I think you're looking at the output of a postscript program that's been post-processed in, e.g. Pshop, to create the symmetrical flop.
I did get something vaguely similar in Pshop by using various sizes of brush tool with the airbrush feature, loadable textures, and overspraying (see below). It's not your example pattern, but I can see how you could get there with experimentation. The postscript program would probably be quicker, though.
