Daz Canvases

How to render canvases in Daz Studio 4.10 and what to do with them in photoshop after they are rendered to make them workable files.
I have been working with Daz for just under a year, so I still stumble around a bit. This is just one way I use canvases, I use them differently for every render, it just depends on what I am needing for that particular art piece. I hope this helps some of you, feel free to leave questions or suggestions.
EDIT: For doing the beauty canvas you do NOT have to select or create a node for it, it can be left unchecked and it will render everything as it is seen in the screen. If you do make a node everything you want to show must be checked or it will not be rendered.
