Stefano,

When I open a file, I check "Leave as is (don't color manage)."
In The Color Settings (Edit, Color Settings) I first set the top overall
"Settings" box to Photoshop 5 defaults. Then I set the top "Working Spaces"
line -- RGB -- to Adobe RGB (1998). That's it.
I just sent you my general instructions for the vm70 curves off list.
Hope this helps.
