poor jpeg output quality
I am currently using the trial version of ON1 Pureraw 2023. I generally like the program and the workflow, in particular the AI noise reduction, and the results look great on the screen while editing the raw files (Olympus .orf). However, when I export to jpg, there is a very noticeable degradation in image quality, with some weird rasterization in areas that should be smooth, like the sky (I was trying to upload a sample image, but it won't let me, although it is smaller than 2MB). I am not sure if I am doing something wrong, but I played around with a lot of export settings to no avail.

Make sure quality is set to 100% and resize is disabled. You may be reducing the quality without knowing it.

Thanks for the quick reply.Yes,I have set quality to 100% and disabled resize. A sample is of the effect is attached below, in particular visible in the sky near the bricks. I don't see this before exporting.

That looks like it might be from the NoNoise AI and/or and sharpening used with it. What happens if you set the Noise Reduction back to the Classic mode? Does that have any affect on the artifacting?

Thanks, that seems to be the case. When I reduce detail and microsharpening to 0 in NoNoise AI, the rasterization is much less pronounced, but still somewhat visible. Maybe I am just pixel peeping at too high of a level.

The sharpening sliders in NoNoise require a very light touch. Too much of either Detail or Microsharpening will produce what you are seeing.

My experience with PR specifically NoNoise is really good. I find the default setting for high detail needs a bit of tweaking: increase the lumenance noise reduction, leave the detail default, usually decrease sharpening a bit. I usually use the structure slider to aid in sharpening.

Thanks for the suggestions, this makes sense.
