As I said that’s my finding as well. But that doesn’t help Peter, nor solve why
he’s experiencing what he’s experiencing. I believe his confusion is common and
relates to how Photoshop calculates color back and forth between these modes
based on his Color Settings. I think he probably created the grayscale file
with sRGB numbers and is then surprised when they change to AdobeRGB numbers…
His new install is probably defaulting to sRGB as the working space...
