Who favours what for fast (more then 400ASA) colour negative film - as I see it there is a choice of:
Portra 800 - does this push sucessfully to 1600?
Fuji G 1600
Fuji Superia 800
Interested to hear any opinions on these.
Superia/Press 800 is the best of the high-speed color print films, with a grain finer than a Kodak 400 or Agfa 200 film, an excellent color reproduction and a wide dynamic range with a realistic, not too soft contrast. It scans therefore extremely well, but I would recommend a soft color paper for direct printing.
Superia/Press 1600 gives the (theoretical) advantage of being an entire f-stop faster, but there is little tolerance left for underexposure. I recommend to expose it rather generously and to avoid it for day-time outdoor photography in general, since its color saturation doesn't match that of the 800-speed brother, and the grain is more pronounced - like a Kodak 400 film ;-)
I don't have any experience with Portra 800.
Gut Licht!
