I'm experiencing colour banding on gradients in photoshop, and it doesn't seem to make a difference whether I choose 8-bit, 16 bit or 32 bit.
From what I read it should be almost impossible to see any banding in 16 or 32 bit because of the trillions of colours photoshop has available to create these.
Just a very simple image with a Black background layer, place on top a fine gradient and reduce the opacity and the colour banding will appear. Then converting to 16 bit or 32 bit, or even starting the new document in 16 bit or 32 bit doesn't make any difference.
Is it that I only see that banding because my graphics card/monitors are not up to the job? Or is it that even at 32 bit colour depth there are still instances where banding is visible to the human eye?
I have uploaded a simple file where you can see this here:
Any tips would be appreciated
