color separation

[Louise Lemieux Berube]

I have a photo in CMYQ and I would like to save separately each channel (in grey scale). 

I am able to see each one on the screen, but I cannot save them individually.

Any help, suggestions?

I am assuming you are using Photo.

Right click on the channels for the selected layer. I assume you have only the one layer. Choose Create Greyscale Layer, then rename it Cyan, whatever you want just to keep track. Then you can copy and paste into a new document if you want.
