What is the best way to create a glow.
I have 2 files, one with a 100% black background.
Another with C50 M50 Y50 K30 background.
I’m trying to create a white radial glow with 100% in the center and 0% knocking out of these 2 backgrounds.
All of my attempts end up banding during the output.
Is there a sure fire right way of achieving a smooth gradation?

Also, why does Photoshop Lounge keep coming during my searches? It’s like some sort of SPAM, I don’t really care about 14 year-old Matt Savage, jazz pianist or Yoko Ono.

’cause the lounge Pandas like to talk about bands? (FYI, the lounge is where we go to goof off and relax and talk about music)

A search for gradient banding reduces the lounge hits

One possible quick solution would be to add a little noise in the layer style’s glow setting.

There are numerous potential sources of banding, from limitations of the file’s bit resolution, or your output device’s limitations. Finding a single cure for every type of banding is impossible.

In 8 bit images, you have 256 steps between 0%-100% opacity (really 256 little ‘bands). If you go from 0%-50%, you’ve just made the bands twice as thick (128 bands).
