best way to create an alpha matte
I’m looking for the best way to handle a problem. I bought an After Effects template for a client Christmas card which consists of a project file completely built in AE (https://www.youtube.com/watch?v=wfIuiSGRWWE). I placed all the photos without a problem, but I’d like to have the ability to make global color adjustments to the composition WITHOUT affecting the photos.
My question: what is the best way to create a pass so I can mask out the photos to use as an alpha mask layer? The only way I can think of is to render a pass where I turn off all lights and assign a luminous white material in place of all the photos. Is there a better way?

Just an add on to your method.
Using a white solid instead of photos is a good way to create Alpha/Luma matte layer. Press AA(press A twice)to reveal Material options of the matte layer and Turn Off Accept Light and Accept Shadows so that it will not get affected by the Environment. This will ensure that the matte will not get affected if in case you miss any light turned on.Vishesh Arora
