Saving channels to png

How do I save RGB specific channels as a png? Whenever I try to save the image with channels disabled the file saves with all channels enabled. If I switch from RGB I lose the option to save as a png.

      Correct answer D Fosse

      Target the channel you want - just click on it in the channels panel - and copy it into a new file. Save/Export that as PNG.

      Target channel. Ctrl A - ctrl C - ctrl N - ctrl V - ctrl E. Save. Do that a few times and it sticks...

      Yeah, Calculations works too.

      Interesting but that doesn't appear to work. The image loses all it's color. Tried it using both Blue and Green and then merging the 2 documents but it just came out as grey scale.


      Fosse's method worked though.


      Thanks to both of you for responding.

      Hi

      I obviously misunderstood your requirement . You said you did not want an RGB document. A single channel Red/Blue or green on its own is just greyscale - it does not have colour info until you put it into an RGB or CMYK document.

      Your right, I should have been clearer in the question. I only wanted to remove a single channel but maintain the other channel colors. I only attempted to switch from RGB because from what I read online that allowed channels to be saved, but as I mentioned in the original question, switching from RGB didn't allow me to save as png which I required.

      Thanks again.

      Hi

      This is one way:

      Use Image >Calculations to create a new document with just the required channel (e.g. here I've shown the red channel).

      In the new document change the Image mode from multichannel to grayscale

      Save As png
