RE: [APML] Konica Centuria super 400

John,  lets see what I get tonight on this stuff, any film is going to be a
tough challenge to Supra 400.  Compare your shot to mine:

Is this a matter of processing or film?  As Dominic has pointed out, the
Konica has a very interesting spectral curve, with a peak in the red at
exactly 650, very close to Ha.  Since I have absolutely no light pollution
at my site here, I think it may be a good base line for others to compare
to.  Lets hope we have a new film for reds!

Um, Dom, before you get too excited let me give you a comparison. I have a
shot of the same region, using the same equipment. The difference is in the
time and the film. The exposure was twice as long at 10 minutes but the film
was Fuji SG100, 1996 vintage. The effective exposure is half of what you
shot as it is only 100ASA. Compare the images:

The Konica looks like a luser to me. Sorry! Hopefully Polaroid works out
better. :)
