any chance for better quality image preview?

Lukasz Szeflinski

There's quite a difference between Photshop and C1 image preview in C1 look at the left side how yellow leaves are splotchy in C1 and everything is more crisp in PS. Any way to make previews better quality ? I set it to 5k but screenshot was taken with that setting.

    Before C1 "saw" the image file for the first time, or after? Any chance that regenerating the preview may improve it?

    Another line of thought: That image is in a Sony raw file. In some cases C1 may display the preview embedded in a raw file rather than processing the raw image to a new preview. Sony embeds low resolution previews in their raw files. Nikon, and also Canon I believe, embeds full resolution previews in their raw image files. It is difficult to see from your screenshot, but I believe PS displays size 6000x4000 pixels. I would expect a Sony preview to be 1616 x 1080 pixels.

    I noticed the same thing. I am still on my trial and even though I really like the results I get from Capture One vs Lightroom I have been noticing these weird smearing effects in the backgrounds of some images. It seems that when the pixel contrast is at a certain level in the image C1 tends to render the preview with this weird smearing effect. It kind of looks like what you get from atmospheric distortion, a weird squiggly smearing effect. It usually only shows up in subtly blurred backgrounds with patterns in them like trees. Of course when zooming in it is fine. The other defect I noticed is that on high contrast areas some big black blocks/lines will show up around the silhouette of the subject. Again, as soon as I zoom in the defects disappear. Maybe I am ignorant but I really do not understand what the problem is. Can they not figure out how to get the GPU to do fast and accurate scaling? I feel like that is image processing 101. For example, I never see these defects in scaled images shown in the web browser. Now when you realize that Google Chrome has faster and more accurate image scaling than a dedicated photo editing application I think we can all see why this industry is having major problems.

    I think similar is known to occur with some GPUs or GPU dirvers. Does it help to deactivate hardware acceleration an regenrate the preview?

    I have not coded graphics for a while myself, but I tend to think the acceleration stuff has been a moving target for quite some time, maybe it still is. Forum users have blamed C1 for artifacts that disappear after updating the graphics card driver. I think we have also seen reports to the opposite, C1 fails with an updated (newer) driver. Setting hardware acceleration off may save the day.

    You may try to submit a request to C1 for a solution...
