Having just shot my first roll of Kodak HIE I have been reading all the
discussion of EI carefully - it seems in common with many people much of
my first roll was heavily overexposed, but as I bracketed +2 to -2 I got
some shots nicely exposed and now have a feel for the range I'm dealing
with. 

However I am very curious about compensation in development - the
comments above imply simply a process of overexposure to get a more
ethereal effect - or are they allied to compensation at developing stage
with undervdevelopment ( a la zone system)?

Does HIE respond to development control in an expected way or does it in
turn vary the IR effect?
