Not currently planned

    Hi Thomas, 
    Thank you for the suggestion - this is not something we are currently working on.

    This does not mean this is a bad suggestion or that it will never be adressed, but in an effort of transparency we want you to know that we are not currently allocating resources to solving this issue.

    We will revisit the status of this thread if and when it changes.

    I've updated this request with more details (and will go over my other requests again). I've read through the template and tried to include everything of relevance to this request.

    That is greatly appreciated Thomas Kyhn – thanks a lot! 


    Damned! I miss this option every single day.

    I honestly do not understand why Capture One stopped on the way. The circles are already implemented.
    Imagine having a 100% zoom (even better make it configurable) pressing the shift key when you move each point. That would be so powerful.

    Actually it's looking more as a bug than anything else....

    Basically, the whole keystone tool would be much more useful if we had 4 independent lines at our disposal - like in Lightroom or ACR. Zoom would be great too!

    There's a request for independent adjustment lines/points here.

    Loupe tool was integrated with Keystone tool in one of the Beta testing package recently. As, I found a bug that it broke exiting Loupe tool, I reported it. My guess is that it was Development (Programming) error not a Design. Surprisingly it was not only removed from that release but also in subsequent releases as well. I don't know why this feature request is shut down...

    I had been asking for the following upgrades in Keystone Tool..

    1. Independent guidelines

    2. Link Loupe tool to aid control points placement precisely. 

    3. Option to lock control points once the position is finalized (may be right-click)

    I've just found a macOS workaround that seems to be decently effective (just used a couple of times in the past ten minutes). Under macOS Ventura (possibly an earlier version too, but I've discovered this feature only now) it is possible to configure the display zoom so that a system loupe is created instead of zooming the whole screen. Below there's the System Settings dialog where the option can be activated.

    Obviously this is not the same thing as a loupe in C1 (that would be able to display more details than those on the screen), but if you have a high density display it might be enough.
