    Fair enough I apologise.

    I thought that was the protocol if a reply doesn't answer your question you down vote it.

    I didn't mean to offend.

    Can you show a screenshot of your export recipe?

    What does the jpg look like when viewed in a browser?

    Looking at your screen-shot in MS Edge using Win 10 I see some variations in crop and maybe some slight difference in the background brightness, mostly on the right side of the image. The main difference is in the orange intensity. Yellow/orange/red are often challenging when compressing for jpgs bit in any case the output as viewed through some other software may give a different result.

     

    In the absence of the active CR3 comparison I think the jpg looks fine as it is . Indeed, perhaps preferable to the brighter oranges of the edit file in some ways. (Depending on intended use.

    How does it look when printed?

    C1 is possibly not the best for jpgs, so I would compare cr3 in C1 with the jpg in a different color managed application like PhotoShop or alike. 

    But if you compare the jpg and cr3 side by side in C1, what is your proofing profile? It should be the same as the recipe profile when you exported the jpg.

    It doesn't make any difference.

    You've been downvoting my reply? 

    Good riddance...

    Because it's not relevant.  It's nothing to do with proofing profiles.

    How do you think I or any of us should know that you are sufficiently familiar with C1 to not make this mistake to view your photos with a wrong profile?

    I was here to help an unknown user with to me unknown experience in C1, but if you don't want my help go figure out the solution without it, just be nice in doing so.

    No worries then.

    For color management (or for weird or unexplainable behavior) in C1 I have a few checkpoints, that's why I asked, but if you have them all ruled out already then just ignore them. The list contains the rather obvious ones like proofing profile with the same profile you exported with, same rendering intent in preferences at export and at proofing time, hardware acceleration off to exclude driver issues, especially after OS updates.

    If the exported jpg looks the same in PS and in C1 then the display of this jpg in C1 is not a problem, what remains is the C1 preview/proofing, or the C1 export itself, or an operating system update in combination with an (older) C1 version.

    As you are running on Apple hardware, if you prepare and export the jpg for aRGB rather than sRGB does that make any difference to the anomalies you see? 

    Also viewing the images at 100% in C1 may make a difference to your RAW file edit choices. Have you looked into that?

    Based on what I can see from your sample screen grab,  the issue relates mostly to the orange colours. 

    I have seen similar things before (in other editors) where strong orange/red colours in jpgs are almost impossible to adjust with any degree of precision because they sit right at the edge of the typical jpg colour gamut capability. aRGB may offer a little more than sRGB in that respect. The problem I have seen previously is that whatever one does in the editor for fine-tuning of gamut edge colours can be quickly undone by jpg compression as well as colour gamut. This may or may not be what you are seeing here but it is something to consider as a possible part of the problem. Such an effect can be further affected by screen handling compression activities. 

    You do not mention your monitor size but your original jpg pixel dimensions would suggest that the jpg is being significantly re-sized for the purpose of creating the screen-shot. 

    One other thing that occurs to me. 

    So far as I can tell you do not have Soft Proofing active in the screen grab.

    Assuming that RAW file is not using the sRGB colour space during processing there may be difference in the colours based on a wider available gamut. 

    If you add some colour readout pins to both images and then experiment with turning soft-proofing on and off, change the colour space in the process recipe and also just in the Proof Profile options you may be able to identify where the anomaly seems to appear.

    Obviously things like the screen's profile and brightness settings can significantly change some aspects of colour presentation where small differences between one image and the next might in some cases appear greater or less depending on the screen hardware settings. However, If you have a fully calibrated screen I assume you are well aware of that aspect. (Others, coming to read this later, may or may not be aware.) 

    In summary I am wondering whether you can successfully display an edited RAW file without Export Proof Profiling applied and an Exported jpg WITH the Proof Profile applied within C1 side by side OR compared using external programs. 

    Viewing the RAW without the export profile applied may result in some of the more challenging gamut edge colours changing quite a lot after export. However, if the two files are displayed side by side within C1 and the Proofing facility IS applied the proof settings will be applied to both images and in certain situations that may mean further, though often subtle, changes to the output jpg file's appearance as well as the RAW file.

     

    Or at least, that is my experience.

    Which is basically the same as that which BeO has already outlined.

    It's nothing to do with where I look at it.  It is very clear to any eye there are marked differences in colour.

    Please refrain from answering unless you have direct experience with this issue.

    The colour difference is the same whether I view in Photoshop or an Iphone or a browser.

    Changing the proofing profile makes no difference.
