This process is relevant to any adjustment layer that you use in Photoshop if you want the same effect on a couple of other images.
You’ve taken some images and found that they are all similar and will need similar adjustments to them. I’ve started with the images that you see below, and I’ve used a levels adjustment on the first image and from there all we are going to do is drag the adjustment layer to the other two images.

Have the other images open that you want to use the adjustment layer on, and simply grab the adjustment layer and drag it to the next image. You should be able to see what I have done in the next image.

Continue doing this until all the images have the adjustment layer. You might have to go back in and tweak the adjustment a little bit if you feel that it requires it, simply double click on the adjustment not the mask and tweak away to your heart’s content.

This can save time if you have a few images to adjust and it doesn’t matter if the images are various sizes, the drag and drop method will still make the correct adjustment.
