Re: [APML] For Wei-Hao :) Will a real astrophoto film please stand up.
Wei-Hao ,
I think you're right when you said " I guess "Centuria" is the real keyword " because I made a search and the centuria super 400 or the centuria super 400 pro have the same spectral curves. These graphics are on the 2nd page on both following link.
here's the link for the centuria super 400 ( PDF )
and the link for centuria super 400 pro ( PDF )
here's where I found these data sheet
Thanks again Wei-Hao !
Dom :)
Hi Dominic,
These are the ones I used:
http://www.ifa.hawaii.edu/~wang/misc/films.jpg
Now even I'm confused by the film names.
The 800 one you have is Centuria Super 800
The 800 one I have is Centuria Super 800 Professional
The 400 one you have is Centuria Super 400
The 400 one I have is Centuria 400 Professional
There are also (in Japan) Centuria Pro 400
(http://konicaminolta.jp/products/consumer/film/lineup/cen400_12ex.html)
and Centuria Portrait 400
(http://konicaminolta.jp/products/consumer/film/lineup/ctp400.html)
Now I hate to figure out the difference between "Super", "Pro",
"400 Pro", or "Pro 400". I guess "Centuria" is the real keyword.

grainy. Both Centuria 800 and 400 don't have the
