I know that! :) . The comments about "Krita not reading floating point 
tiffs" and "tiffs having various ways to write files" weren't meant to 
be read as causally linked in any way! But I've been attempting to share 
floating point tiffs between different editing applications for several 
years now, and there does seem to often be a "communication gap". I've 
never had an OpenEXR image not open correctly when shared between 
applications that read and write OpenEXR, as long as the right ICC 
profile is assigned upon opening.
