Hello friends, when I edit my black and white photos in Photoshop I always end up getting sky in rainbow layers like in the attached photo. Is there a good way of removing the layers or making them flat or anything else could be done. Thank you all kindly in advance for your help.

Gradient banding is what happens when there isn't enough tonal range for the different colors in a gradient. You can fix it by increasing the image from 8 bit to 16 bit and applying a blur to the selected gradient. Here's an article I found that describes the issue more and gives steps for fixing it.

Semaphoric, the combination of 16 bit and blur with little noise as suggested by Myra seems to work well. Thank you.

Hi

First off work in 16 bits per channel which will avoid banding, however you may still see banding on your screen if you are not using a 10 bit monitor. That is on your display only though not in your image.

As suggested by Semaphoric, adding a little noise is effective at reducing banding if you are forced to work in 8 bits/channel

Hello Dave, I tried 16 bit editing and blur around banding areas, it seems to be working for me so far mate, really appreciate. Cheers.
