thank you very much, great advice. 

[plate layer?]

Hi, 

I have been following some youtube tuts and one thing I've heard thrown around in photoshop is something called a "plate layer" or "plate setting,"in context with placing a base image such as an empty scene and another with the subject but some other objects (such as the OCF soft box) that need to be edited out. My question is does AP have something like this? 

 

Thank you for any info 

 

Mike
