See noise reduction results in proof mode regardless of preview size setting in preferences

Permanently deleted user

Since CO 21, the ability to see the results of noise reduction in proofing mode depends on the size of the preview image set in Preferences - Image.

If the output recipe is smaller than the preview image setting, the noise reduction results are not visible even at 100% magnification. 

Example - recipe is a 1600x1200 jpeg, preview image size is set to 2560. If proof mode is on, the noise reduction does not show even at 100% magnification. That is, moving any noise reduction sliders have no effect and the image appears as if there was no noise reduction applied.

The workaround is to set the preview size to a smaller number, which presumably causes the CO engine to go back to the raw file to process noise reduction. However, this has adverse effect on the performance of other tools, especially with multiple layers.

This used to work ok in CO 20 - that is, the noise reduction was visible in proof mode, not just at 100%, but at any magnification.

I understand that in regular mode, it makes sense to only show noise reduction with larger magnifications. However, I believe proof mode is supposed to show the image exactly as it is going to be exported and it is tolerable if noise reduction introduces a performance hit. Or just make the behavior a preference setting.

    I understand that in regular mode, it makes sense to only show noise reduction with larger magnifications.

    With some images even this is not true, high noise images can result in color shifts (e.g. magenta) in the preview when you zoom out  to fit (e.g. zoom level 17%).

    So the zoom level at which all adjustments are applied should be a general preference setting, imo. But your case actually sounds like a regression defect, I would consider to submit a request and call it a bug, if I were you.

    Thanks I logged this. I logged this previously during the 21 beta, but got the answer that it was likely a design decision to improve performance. However, more people ran into this since, so I will try to raise this as a regression defect.

    Better performance is always a good idea,

    however it should not come for the price of image output or image preview quality or accuracy, or at least should be configurable.

    I really think this is a bug you should report as such. Or did they change this meanwhile?

    I don't think they changed it. This question came up in some Facebook groups as well and I suggested everyone to log this with Capture One support. I am not sure - is there a way to log a bug any differently?

    The only way I know is via this website.
