Hello. I am certain that my R, G, and B colour information alpha channels used to be entirely greyscale. Now I see transparency in them. I can't find a way to revert to greyscale with no transparent areas.

Any help is appreciated.

Thanks.

What version of photoshop and operating system are you using?

 

Can you post a screenshot(s)?

 

Check the Layer Opacity and Fill Opacity to verify they are 100%

Transparency in the layer will show up as transparency in the channels. If you don't want layer transparency, flatten the image (make a copy first).

Within the Transparency & Gamut tab of the Photoshop Preferences is a section called Transparency Settings. Does setting the Grid Size to None achieve what you want?

That does work, thanks for taking the time. But it also applies to the Layers as well as the Channels.

I'm not complaining about the Channels. Just convinced that it was different before.

The alpha channel called "Blue copy" does not have transparency. 

 

What is your goal in "not seeing" transparency in the three color channels? Do you want a flat image or do you want to hide the grid or something else?

I believe the alpha channel without transparency was what the OP wanted to see. The first blue channel does show transparency.

Thanks everyone. I can work with the colour channels the way they are now. But I am sure that the RGB colour channels didn't have any transparency before. Just 8 bit greyscale. I may be wrong. I am getting very old...

You can add a Background layer or add a new layer (white) at the bottom of layers.

Thanks again, everyone. I am not really complaining. Just trying to find out whether it was Photoshop that changed, or my brain...
