Hi,

please could someone direct me a guide on how to apply the above.

i have a headland , so surrounded by water which makes sky replacement not effective. So, I'm looking to select the headland in the initial image (first) layer then apply it to subsequent Milky Way images, from which I'll convert to jpg and make a Timelapse. I've seen many like this so know it's possible and should be easy, but as much as I've tried searching, I'm coming up with everything except what I'm trying to do.

thanks

I have Photoshop, lightroom, lightroom classic and LRTimelapse (if the latter helps )

Have you isolated the change to its own layer, or is the change part of the original layer? I'm thinking that layer comps should be useful.

Providing a layered file with at least 3 layers would help, even at a reduced resolution. A screenshot of the layers panel with thumbnails is also useful to help understand the file structure.

Thanks for the reply. I think my original post probably wasn't as clear as it should have been. (I blame age)

I've attached am image.
im looking to apply the selection (though it would be selected accurately) to the other layers

hope this helps

The selection is independent of the layers... Apply the selection how?

Do you wish to copy the selected, previously adjusted "baked-in" pixels of the top layer to all lower layers, perhaps via copy/paste?

Do you wish to apply a recorded action that adjusts the pixels in one layer and run the selection and action to all other selected layers?

You can semi-automate this via an action, which would be run for each layer, then it would select the next layer, then you would rerun the action again as many times as required. Otherwise a script could loop over all layers automatically.
