Re: [APML] Centuria 400 - Photographic Results II



Chris,

Very interesting and useful work.  Some of those results may be better than 
they appear at first.  I tested this film sometime around 1998 and thought 
the results showed some promise.  Of course the film may have changed since 
then.  At the time I thought the reds had a somewhat "muddy-brown" colour, 
but otherwise the Ha response was pretty decent.  One thing that is very 
good with this film is the OIII crossover - currently this may be one of 
the few colour neg films around that tries to record the visible spectrum 
accurately.  I think this film has potential and is worth testing further - 
the only reason I didn't pursue it back in 1998 was that PJM-2 and PPF were 
available at the time.  It's hard to understand why the quality problems 
exist - the rolls I tested all seemed to be fine.  Another thing worth 
mentioning is that there used to be a 120 format version of this film - not 
sure if that's still the case.
