Is possible to copy-apply layer adjustments?

NNN635656747947842588
Is there any way to copy a layer from a photo and paste to another one?
Or copy the adjustments of one photo layer and apply to another photo layer?

I know I can copy adjustments and then apply to another photo, but this way applies ALL (layers, masks,exposure, etc)

I have some photos, the first only with the background, and the rest with a subjet in front ... so I like to adjust the first, open the second, made a layer to mask the background, apply the saved adjustments only to this layer and leave the subjet apart of this adjustments, to adjust it in another way.

Is possible?

    Not sure why, but layers and "background layer" on local adjustments aren´t acumulative as said here. And they haven´t the same effect.

    If you move local background layer exposure slider to +4, by example, and then add a layer and move to -4, you DONT GET 0 exposure. It will result in a darker image, than before, maybe -1 or -2 EV.


    Well I have to admit that I've never advanced into testing whether equal numeric opposite corrections applied on the "BG" and a LA compensate precisely. But they add up, I'm pretty sure - what else those are numeric operations.

    Perhaps worth to check: the opacity setting for the LA masks. If opacity is not 100% I wouldn't expect for example a certain +4 LA setting compensating a -4 setting of the same parameter on the "BG".


    It´s at 100%.

    Hmm, it may be coincidence but in a brief test where I checked the brightness data of a defined spot took note of the value, then setting an exposure correction of +0,3EV, then creating a LA layer, paint a mask (100% opacity) over the spot and making a -0,3EV exposure correction I found the brightness value back at were I started.

    So C1 seems to work exactly as said in an earlier reply. I just didn't have checked it by myself.

    After read that, I did some test, because I think maybe 0,3 EV is a little change to see it . I did a +4 EV correction (just for test) and then -4EV again on a layer and the result isn´t the same.

    And If I restore to the original raw I can see how it turns more bright...

    So, I was triying, and is at 4 EV when the problem appears... less than 4EV does not have this effect... I don´t know why...

    Well 4 EV is more than I never needed to adjust... so I can ignore this, but the fact is I still get a washed photo if I apply the adjustments I made to the first one on the bacground as a layer on the second one.

    Maybe is due to the adjustment sliders that appears inactive on a layer, and are active on the background....I am not sure yet.

    As mentioned, I hadn't tested this before now recently. And for me it seems to compensate perfectly.

    When greater adjustments are used though I think things can be different indeed. So I could imagine that a +4EV adjustment just sends the values into space. I have no idea about how the numeric operations are performed but I suppose the shown 255 brightness value are limits - and this could mean many middle to high default image brightness levels are shifted to plain 255 by a +4EV adjustment (and not more). For this reason I'd not expect a subsequent -4EV adjustment via LA bringing the values back to where they were.
