Exported Jpeg differs from C1

Hello,

I have a problem when exporting Jpegs from a TIF file (negative scan). They look sharper, more noisy and brighter than in C1. Plus the spot removal areas are quiet dark, close to black after exporting.

I am working on a 2017 Macbook Pro 13 without Touch Bar. The display is hardware calibrated.
-> Changing the ICC-Profile of the file and for export settings makes no difference.
-> hardware acceleration has been turned off and on again, also I deleted the folder, so it calibrated again
-> I deactivated OpenCL, but no difference
-> I reset all the settings in C1 without any difference
-> Exporting as Jpeg "QuickProof" results in a Jpeg without any problems.

Furthermore I have noticed that the Viewer shows a different picture as soon as I zoom closer than 29%. For example the spot removal areas are like mentioned before.

I looked for similar problems but couldn't find anything helpful yet.

    Mac or Windows?

    How do you view your exported JPEGs?

    I am using MacOS Mojave 10.14.6

    I view the Jpegs with Quick Look and Preview, no difference. Also I sent the files to my iPhone. Same behavior.

    Sorry I missed your Macbook statement in your first post.

    I can not think of a reasonable explanation. Could you post some screenshots perhaps? You can post images by pasting the internet link in a post.

    This is a screenshot from C1. The way the picture should look.

    This is a screenshot of the exported JPEG.


    The file I am working on is a TIF file from a negativ scan.

    Unfortunately, I can no see the screenshots. I see a small icon with a question mark. Could you edit your post or post again with the same links but without the tag?

    Thanks. Regarding spot removal, have you used the Dust or Spot option? I would think that the Dust option works better. But I am not sure since you mentioned working with a negative. That might confusion that feature.

    Thank you Paul but that didn't work. Nothing happens at all. I tried the spot removal on a RAW file, it worked perfectly but with this negative scan it's not. The dark areas are created by the dust removal, because there was non before. I can randomly click on a clean part of the picture and it will create a dark area. But let's forget about those areas. The overall problem is that the exported image does not look like the one C1 shows me while editing. Like I said in my first post: sharper, more noisy and brighter. This problem only occurs with Tif files from a negative scan (scanner is a Hasselblad x5), not with my RAW files from a digital camera.

    Is there anything I have to pay attention to? A setting I am missing?
    Or is C1 just not capable working with those files?

    Thank you for your help!

    I think that the combination of the inverted files is not working right with the calculations of the spot removal tool. In other words, the spot removal tool is not working properly on inverted files.

    I suggest you make a feature request for this by opening a support case.
