Title: Shot ISO 160 film as ISO 400, should I trash it?
Post by: haring on February 13, 2013, 07:56:46 pm
Please don't laugh!

I have shot two rolls of ISO 160 film last week. The camera was set to ISO 400, should I trash the two rolls? Is sending them to the lab a waste of money?

Thanks!

I'm not laughing! You are not the first person to do something as such. If you are using a custom lab, they should be able to push them for you in development.

Good Luck,

Is this tranny or neg?
If tranny get a clip test at push 1.5 stops, if neg just run the rolls at push 1.5

The prints will have a nice bit of "filmic" grain. Lovely.

Send it to the lab. It is amazing what you can get from underexposed film. You can ask them to push it a stop, otherwise just normal processing. Scan and process.

since you mentioned "160" film, I'm assuming color neg.

Tell the lab to push the film 1.5(or if possible, 1 2/3 stops) in development.

Your shadows won't have super duper detail, since they're underexposed, but modern films are generally fine with some underexposure(within reason).

DON'T RUN IT (NORMAL). You'll have muddy film with bad shadow separations(at least IME). Push it 1.5-1 2/3 stops

I would not worry about normal development--you can get your contrast back by scanning and processing. Pushing is not always ideal--it is simply overdevelopment. That will be simply adding contrast, but if the contrast change is not uniform with each color layer, then you get cross curves. So, if you have no option to push process, process normally.

I would not throw away such film and try to get useable images. You can consider using resulting images in BW. This can provide content yet hide problems with mentioned color issues if they arise.

who knows maybe something magical comes out of it? ;)

The best thing is you realized what you did before development.   :)

I love pushing color film.  1.5 stops isn't extreme.  I've always considered the box speeds to be suggestions, even with color.  At 1.5 stops the color shouldn't be off, just shadows might be a bit muddy when pushed.  Grain won't be a serious problem in midtones assuming you were shooting Portra 160 or Fuji 160c or s.  Its only two rolls, so what's $8-$15?  Might be fantastic.
