[alt-photo] color separations in Photoshop

Folks--In Photoshop when I have an image (RGB) and use the channels box to
make separations the resulting files are Grayscale. I can, of course,
convert them to RGB. My problem is that after I apply my curve there is a
difference between the images left grayscale and those converted to RGB.
Now, I derived the curves using the common 10 x 10 square which was, of
course, in RGB --so it seems likely that I should convert.
I don't remember seeing this discussed anywhere.
Advise (yes, I'll try both ways if I need to).
Thanks Charles Portland Oregon
