Colour banding in exported JPG
This may have been answered before, but I can't find it.
Are there export settings from RAW originals to JPEG that eliminates or reduces banding in graduated tones such as the sky?
Currently using 2000 long edge, 150 ppi, JPEG, quality 80, Apple RGB. Images are usually posted on Flickr.
I have tried many combinations, but still get colour banding in the exported image. The banding does not show in the RAW image.

You might take a look at this thread for some ideas...

I have this problem too. At 100% jpg quality it is less pronounced. A LR export with the same settings has much better IQ. It’s the banding in sky colors but also resolution or clarity is much less from a ON1 export

Have you used the Soft Proofing feature to check for color shifts in different color spaces before you do the export? Go to View > Soft Proofing and turn it on. Then you can choose different colorspaces from the View > Profiles sub-menu. The Simulate Paper and Ink option will highlight out of gamut colors similar to the Highlights & Shadows indicators with the histogram.
If you see any disagreeable color shifts you can use any of the color management filters to correct for them before exporting. You can create versions so the color corrections are specific to online display and sRGB or printing with Adobe RGB or ProPhoto depending upon your printer.

Rick, the article did not really help.
Brian, I did not see any colour shifts using the soft proof. If I did print, I did not get banding on the prints, but this is about exported JPEG's for display. Even on my computer, the exported JPEG is showing banding before it is posted.

Chris, I think the main issue here is your raw file is probably 12, 14 or 16 bit file. The color range these files can support is much greater than what an 8 bit jpg file can support. I think with a smooth color change as in your photo ( which is very nice by the way ) might always show banding when converted to JPG from a Raw file. For a photo like this you might want to try the Png or Tif formats if your display platform supports it. I'm pretty sure the Tif format will keep the original bit level of your raw file and you shouldn't see this banding. Not sure about PNG but I think it will.

David your reasons makes sense. PNG does still show the banding, but somehow is missing the metadata. Will try a few more combinations to see if there is any magic left. This photo may have been extreme case for the graduated tone across the entire image to expect a good conversion.

Today I had the same problem. I realized that when I export JPG, even though I want to export the same resolution, I need to set resize and set it to something like 10Mb 300dpi.
Doing that the quality and banding disappear. If I try to export without any resizing, there is a lot of banding.
I think something needs to be fixed there. Now using ON1 2022 still happens this.0 -
Are you exporting at 8 bit or 16 bit? 16 bit shouldn't have banding.

It happens when you export a JPG directly from ON1. Just a simple resize on a JPG degrades the quality when exporting JPG adding a lot of banding, unless you resize.

You can post a screenshot of your export settings for us to check if you like. Otherwise I'd suggest that you send banding examples in for On1 support to check out.

Direct export when banding happens.

There is no option for bit depth in Export, so I don't know if it's 8 or 16. Someone else was asking about this recently but I can't find the post.
However, in settings for sending a file to another editor, there is an option...
If you set this to 16 and then simulate sending the photo, it will create the new image in the same folder and you might get a better result. That's my only suggestion, if instead you want answers for Export, you'll have to ask ON1 tech support about that.

Thank you Rick. So far the solution I use seems to work, but shouldn't be this workaround just to export a JPG.

The thing is, I don't have this problem. Never have had. I don't know why you're having it and the workaround is just for you. If you want actual answers, you need to talk to tech support and let them check it out.
