Banding in Action

[Gyuri]

Hi,

Could you guys tell me please what settings should I change to avoid banding in Action?
The setup is really simple. I load a 16bit fp white image to Action, bend it with bicubic and put a single light in. Spread is 67 and falloff is 7%. The action setup is 16 bit fp, Clamp Colours are turned off.

Cheers,

pH.

Hi PixelHussar

I´m working with nuke now. But I had the same problem with this!
Try to change the softness into the setup menu. Into the setup menu there are some values that you can change and avoid this problem!

I hope I´ve helped!

Cheers!

Also try adding grain to your result.

Honestly…In the many years of dealing with this issue, I do believe you can eliminate alot of the banding…but I have never been able to completely get rid of it totally! Even if you think its gone..look closely…there’s still a hint of it.

Add a simple noise/dither and you should be fine.

Bluring/softening will usually make it worst. And I wouldn’t recommend using grain since it’s way too different from noise and it might end up giving a texture to the final material that is not desirable.

Thanks for your tips guys. I try to live with this issue.

Technically speaking, the image is only banding on your display a case like this. The way to prove that is to add the smallest amount of grain. Blammo, no more banding.

What this means is that your image, as an image, doesn’t actually have banding and you don’t HAVE to add grain to it to “Fix” it, but due to the nature of various monitors and displays, you may want to add some.
