Hi,
This is my first time asking for help on a forum and please excuse my english.

I am working at some underwater world painting in photoshop CS3 and a notice that when I use eraser (airbrush soft round) on some layer that is transparent (say 80%) I got banding.

My document is 8000 X 4000 pix 72 dpi RGB 8bits/channel.
I have attached the JPG example with my problem

PLEASE HELP

Adrian

Lo único que puedes hacer es aplicar un filtro suave de ruido a esa capa. Eso hace que el banding desaparezca, pero hay que conseguir que el ruido no sea muy fuerte. Ve probando.

The only thing you can do is to apply a noise filter to that layer. That will make the banding disapperar, but you have to manage not to push the noise to far. Try it

Well, I had the same problem with something I was working on.
It was a pretty dark environment and both eraser and soft brushes resulted in banded colours.
Then a colleague pointed out that my value space was way too narrow.
In practice, say, I was trying to paint a smooth gradient between point A and point B, but the difference in value from the two points wasn't enough.

If, for example, A has a value of 7 and B a value of 10 there are only 2 values available between the two points, hence the bands.
Your drawing seems pretty dark too, can it be the case?

I hope I made sense, it's difficult to explain with no images

I get the same problem all the time and it's quite annoying. I still haven't figured out how to fix it.
