Is it really impossible to have gradient without banding?
I am struggling to create a gradient without banding. I have watched all the videos on YT and tried: Bluring all kinds, Noise, Dither,bit depth, Brush and doing the gradient in Illustrator.
Everything fails and I can always see the banding.
The background color I use behind the image: 050b3c
Noise and dither usually yield quite good results. There's a couple of things that may make â€œbandingâ€ more apparent:
- â€œstartâ€ and â€œstopâ€ colors
- gradient size (banding becomes more apparent when â€œstartâ€ and â€œstopâ€ points are getting farther from each otherâ€”gradient have to be â€œprojectedâ€ on more samples with the constant number of available brightness values),
- miscallibrated/poor quality monitor (have you tried to view your gradients on different monitors?),
- reduced â€œper-channelâ€ color resolution in system settings (seems unlikely nowadays since most systems use 32 bps settings, but still a possibility),
- â€œwildâ€ video card gamma settings (e.g. in â€œvideo card control panelâ€ or gamme loader like Adobe Gamma Loader),
- too â€œagressiveâ€ monitor profile (again view-on-other-monitors test should provide some hints about it),
- reduced bit depth of an image.
Also it would be useful to know what your target device is. There's a difference how much you can â€œspreadâ€ your gradient whether you're targeting print (what kind of print also matters e.g.: screens like AM, pseudo-stochastic, stochastic) computer monitors or mobile devices displays. It also makes difference then wether you use raster graphics or vector graphics.
Bottom line is: this is quite complex subject :).
