Can Luma curves not be copied ?

Permanently deleted user
I find this strange.

I adjusted an image using curves, both Luma and RGB.

I click on the "double-arrow", verify that "curve" is well ticked, click "copy".
Go to the next image, very similar. Click on the "double-arrow", verify that "curve" is well ticked, click "Apply".

And nothing.

I try again, but this time, copying using the small "double-arrow", and pasting using the "big" double-arrow in the menu bar. Works.
Why ? Am I doing something wrong ?

    See the RED text.

    Do not do this. Nor, really, do you need to recheck the ticked selections unless you feel you want to make doubly sure of your settings.

    It will copy the settings from the current PRIMARY variant - the one you have just selected.

    To make it easier to see what happens open up a floating Adjustments Clipboard tool before do you copying. (Or simply use the command in the floating tool.)

    Using keyboard shortcuts there are various way you can control the data copy making it just a single activity if that will be suitable. HOWEVER, understanding the controls and options may be very important for the things you want to to if selective copying and pasting is part of your plan. (Things are much simpler if you just want to copy everything without being selective in any way. As you might expect.)

    In the two stage process you are first populating the Clipboard with ALL of the available data from the source file currently highlighted.

    The clipboard tick selection controls will be set according to the "rules" found by clicking the "..." symbol at the top of the Clipboard tool.

    You can then removed the selections or add other adjustments should you wish before "Pasting" the selected changes to the target variant(s).

    Note that you can preselect the Primary (i.e. source) image and the target image(s) in order to make the transfer in a single action if you know you will not want to change the tick selections of the available adjustments.

    In the Clipboard tool you can see on the top line the name of the file from which the current clipboard adjustments have been obtained.

    HTH.

    Thank you once more, Grant, this time for a rather complex reply.

    I will have to re-read it then I have more time, to be sure I understand the logic of the developers.
    But definitely that will help.

    It's really quite simple and elegant to do. Far more difficult to explan and cover as many angles as possible using words.

    And I think we nearly all tend to fall into a small trap of making things more complicated than they are by making assumptions. I know I have done so many times - including for the copy function.

    The way I have mostly used it for years is to simply copy and paste everything from one image to the next group (single image or multiples.) 99% of the time that is fine for my workflow and I adjust the results as needed after copying over.

    Recently, prompted by some posts in the forum, I decided to spend a little more time investigating in greater detail. Partly the V20 update and changed to the Layer copying suggested that I should dig deeper at this time.

    At that point it became a little more obvious that it is quite easy to assume complexity where none really exists. I think most people will do that from time to time - I certainly do.

    So taking some time and working with a tool, posing some self suggested "What if?..." questions, seems to be a very good way to discover its capabilities and become entirely familiar with its workings.

    Once understood the ability to apply it comes more naturally. Indeed the ability to MANAGE it according the needs of the moment and then apply it comes more naturally.

    At least that is my experience.

    To answer the last question, yes. I will try to explain.

    The double-arrow on the tool opens a small clipboard, as you know. In this dialog, there are two options, Copy and Apply. Here start the confusion.

    You have to understand that in Capture One you copy adjustments from the source image (a.k.a. the primary variant) to a clipboard, and apply it from the clipboard to the target image.

    Copy in the double-arrow dialog means: copy the adjustment to the clipboard, and do not apply yet.
    To apply it later, you selecte the target image, and you apply the adjustment with the Shift+Cmd+V shortcut or Adjustments menu > Apply Adjustments. Do not open the double-arrow dialog again. (this is what Grant meant to say, I think).

    Apply in the double-arrow dialog means Copy and Apply! This is very fast and convenient when you have selected both the source image and the target image(s). The target image instantly get the adjustment from the primary variant. Note that the clipboard is still used in the background.

    When you look at your sequence of actions with this knowledge, you understand that in step 2 you went to your target image and copied nothing from that image onto itself.

    Sound correct - you are a great teacher.

    What about "shift-double-small-arrows" then ? If I understand it correctly, it copy/pastes the adjustments to all the selected images ? With or without "Edit all selected" ?

    How can I be sure that the requested checkboxes are ticked, w/o verifying ?

    Pressing Shift with double-small-arrows only suppresses the dialog, making for an even faster workflow. It has nothing to do with the "Edit all selected". This option must be ON to make it work.

    Suppressing the dialog removes to options to control the checkboxes. Checkboxes are always ticked for the adjustments made. In other words, Curve has only 1 checkbox, so it will be ticked if you made any Curve adjustment.
    Exposure tool has 4 checkboxes and only those which were adjusted, are ticked.

    Playing around deliberately helps a lot in getting to know these features and get it into your muscle memory.
