Re: [APML] Agfa Colour Optima 400

Hi George,

I always thought this film had some potential - I took a couple of very 
limited test exposures but unfortunately never took it further because PPF 
was still around at that time.  The test exposures were taken in poor 
conditions so didn't reveal very much, but even so I thought the film has 
potential.  Philipp Keller was also experimenting with it and sent me a 
couple of test negatives because we were running tests on scanners at the 
time.  His results were much better than mine - I am sure Philipp wouldn't 
mind me showing them:

Philipp took the following two images in Namibia using the same equipment, 
and I think the conditions were pretty much identical.  The first one was 
exposed on Fuji NHG II 800:

And the second one was exposed on Agfa Optima 400:
http://www.astrocruise.com/misc/b33_opt.jpg

They are both medium format raw scans, scanned on my Sprintscan 45 
Ultra.  There is a strange artefact in both images near the Horsehead - 
this is an optical reflection.

I think the comparison is quite interesting.  The Optima curves have 
characteristics that are quite close to the Kodak films we were using at 
the time.
