Action To Add A Layer Mask To ALL Layers?

  • February 3, 2017

Is it possible to make an action to add a (black) layer mask to ALL layers?

 

I know how to select all layers.

 

After I have selected them, the Layer Mask option is Greyed Out though under the Layer menu (oddly enough, I can apply an adjustment layer to ALL layers, but not a layer mask!)

 

Unfortunately, putting the layers into a group and then masking the entire group will not work for me.

 

Is there a way that photoshop can "step through" the different layers and mask them one at a time at least?

 

I usually have somewhere between 4 to 10 layers per file (it varies from file to file), and it is a bit tedious doing this by hand on every layer.

 

Thanks in advance.

Correct answer Easy Mark

Yes, your example is how you would do it -- set up the number of layers you want, press record and add a layer mask to each layer one at a time, then stop. If you run the action on a file with fewer than the 5 layers in your example, a message will appear and you can either click Continue or Stop.

There is a a post, a couple of years old now, that presents a script for doing what you want:

Script to add layer mask to all layers but background?

So you might give that a whirl.


Thank you again for the response, Barbara. With your help, I figured out how to do it!!!

I used one of the scripts in the post to which you linked, and it works fine.

Now, I wanted to first Align all the layers (it is kind of like an HDR image where there are several frames at different exposures), so I created an action, used the Select All Layers, then Edit -> Auto Align Layers

Next thing was to add a step in the action which selects the TOP layer (this was important for some reason - without it, the masking script didn't work). So - while still recording - press your alt and your . keys at the same time (I guess that is option + . on a Mac)

Then final step was to click the flyout menu of the action pallet, select the Insert Menu Item, and then navigate to the script that will mask all the layers.

That middle part where you have to select the top layer needs to be run otherwise it won't mask the top layer.

Thanks again. I am a happy camper!!!

I just hacked a slightly different script just in case anybody else is looking for an updated solution for 2021.

The script link in Barbara's post no longer works. For those looking for a similar script:

This script is not compatible with Photoshop 2021.  Can anyone update it or give a link to a version to that is compatible.

Is there an error reported? If so please post a cropped screenshot. It may also help to post a cropped screenshot of your expanded layers panel.

Layer masks must be added to layers one layer at a time. However, you could create an action that adds a layer mask to each layer one at a time. If the files you're working with all have the same number of layers, the action will complete successfully. If each file has a different number of layers, a message will appear when running the action, and you'll need to either click 'Continue' or 'Stop'.

If you want to have an identical layer mask on all layers, you could first group the layers and have an action that adds a layer mask to the whole group.

Thank you for your response, Barbara:

Unfortunately, grouping layers won't work for my needs. I end up blending DIFFERENT PARTS of different layers to make up the final image.

Could you explain to me how to "create an action that adds a layer mask to each layer one at a time"? I know how to record an action. But after pressing the record button, how would I have it cycle through the layers?

Should I just create a document with - for example - five layers - and press the record button and then add a layer mask to those five layers, and then hit the stop button?

Thanks in advance.

And if you have any influence on the powers that be, could you communicate to them that having the ability to apply a layer mask to ALL layers would be appreciated, since it seems it is possible to apply an adjustment layer to all layers without having to group them.
