Hi,

Im try to create the circular bumps on the Sabian cymbal below, and cant find a good way to do it in Photoshop, any ideas about how how would go about doing it?

i tried by manually making circles but its extremely time consuming, and very inaccurate.

For which program?

In 3dsMax I would use a anisotrpoic shader and a radial gradient ramp for the bump with lots of black and white flags.
