Photoshop mask and transparency settings
I've created a mask on a copy of my background layer which is hidden. I've masked out all the background. While working on this, I had my Preferences/Transparency Settings set to Grid size small Grid color blue. The background is knocked out. If I turn the Transparency to None, part of what is supposed to be hidden is visibile. I have renamed the file and rebooted my Windows 10 PC. Photoshop version is 20.0.6 Screen images included

Thanks for any insight
