NPS 160 Quickload

[Sara P]

Going to be shooting NPS 160 next week in my Toyo 4x5...I read here on other posts that people rate it at ISO 100...I was wondering, if
I shoot it at that ISO does my lab still process it at normal?
Thanks...sara

The main reason for overexposing color negative film is to assure that sufficient shadow detail is captured. It should be processed normally.

[David Roossien]

Yes. You expose more, the lab develops normally.

It's best to do your own tests. To just go ahead and set the asa to 100 because others are doing it is a waste of time and film IMHO. Thru experience I rate the asa of NPS at various rates based on the subject matter and lighting.

You main find like me that 160 is just fine for most situations. A lot of it boils down to how you meter, or which way your meter is biased if at all.

After years of testing all the so called "160" speed color negative films and found them consistently to be closer to 100, I quite testing unless a new design is introduced. As it stands, I have shot NPS, Pro 160 S and all the "160" speed color negative films from Fuji and Kodak at asa 100 for twenty+ years now. I also worked at a color lab printing C-41 and nothing printed (or now scans) as well as a properly exposed asa 100 rated 160 color neg. Prints from the films rated at 160 consistently have poor shadow detail and weak blacks because these films are really slower than they are rated.

I'm in the "rate it at 100" camp. I tried it once at 160, it proved insufficient, and 100 has worked very well ever since.

I'm rate all at 125 ASA the 160 ASA and the 400 ASA at 320 ASA. Its how it works for me best!

Good luck, Armin

For pro commercial photographers, rating the film at 100 has another benefit, it then matches 100 speed Polaroid and you do not have to interpolate exposures from test to real film.

Thanks for the replies guys...really appreciate it...Rating it at 100 will be helpful as I am using polaroid for testing the shots...

It is commonly accepted practice to expose at a slower film speed than given with negative film. This was commonly done with the guise that the rate given was higher than the actual or working ASA (ISO).

Acually, overexposing by a 1/3 of a stop results in higher saturation which is basically what the manufactures finally did & produced as high saturation or intense color saturated films.
