Re: [APML] Another Color Negative Film?

[Philip Perkins <philip@astrocruise.com>]

I wish this could be a new astro film but they have killed the Ha response 
(see the curve at the URL below) - unfortunately I doubt very much that it 
will record hydrogen emission regions.  Also the OIII response is typical 
for Kodak - it's all green with virtually no blue (the OIII line should 
record almost equal amounts of green and blue).  This means that Ha regions 
will come out looking orangey-red instead of pinkish-red.

Also I am confused why Kodak is releasing most of their films in only 35mm 
format.  The 35mm market is being rapidly overtaken by digital cameras - 
it's in medium format where film still has a strong edge over digital 
cameras (at least amateur affordable ones).  Supra is another example 
that's only available in 35mm format.  It's only Kodak who are doing this - 
Fuji, Agfa, and Konica all release Pro films in 120 format as well.

The 120 format situation is quite depressing at the moment (for colour 
negative which is all I do) - I am thinking of giving Agfa Optima 400 
another try - my initial results a while back were fairly encouraging.
