Dither Gradients Preference and Gradient Banding?

Recommended Posts

FYI, this question has to do with AP:

 

Looking at a recent image, I noticed some faint banding that was visible when I applied a color gradient (maybe it was there in the B&W version, but I couldn't see it). See the darker of these two images: https://forum.affinity.serif.com/index.php?/topic/20687-photos-from-a-mountaintop/(FWIW, I see the banding on my non-retina, late 2013 iMac; I haven't checked on other machines).

 

Searching the forums I came across a comment about the "Dither Gradients" preference and the different effects if you are working in 8-bit or 16-bit (see MEB's comments in this thread: https://forum.affinity.serif.com/index.php?/topic/13742-unwanted-noise-in-gradients).

 

So, my question: If I'm working in 16-bit, is it better to leave "Dither Gradients" preference checked? Or unchecked?

 

Thanks,

Darin

Hi, I have dither gradients, and no matter what I do I have banding, I tried also to work in 16bits, then convert to 8bits (flattened image), and nothing fixes the banding, when you work in 16bits in photoshop and then you flaten image and convert to 8 bits, it applies a perfect dither and no banding is there. This gradient is added from a layer style, is there possible to fix this?
