Fuji Neopan Acros 100 - Shot by mistake at 120 - What should I do?

[pressureworld]

I shot Acros 100 (120 film) and shot it 120 by mistake instead of 100. All the shots were long exposures using the the Hassy.
Do I develop as normal? or push it a stop? or throw it out? Please help!!

O you mean 125? That's only a third stop less. How do your negs look when you shoot them at 100? If fine, then I probably wouldn't worry.

Do nothing or push half stop. Don't throw it out. Not a big deal.

Do nothing. Your figure is more likey 125. Insignificant to ACROS and many other films, if it was transparency (slide) film, it would have a small bearing.

I would process as normal and not even worry about it. You say these were long exposures. Did you compensate for reciprocity failure? If not then long exposures are somewhat hit and miss anyway. You have not even made a half stop error by setting at 120 instead of 100. Many cameras can’t even do apertures or shutter speeds to half stop accuracy so don’t stress.

I'm grateful for the quick feedback. I will develop normally. I was worried because this is my first time shooting with this film. The shots are all long exposures, and I did compensate for reciprocity failure when needed.

One third of a stop is well within metering variations (not only meter inaccuracy but choices made in metering technique). It won't make much difference.

And Acros doesn't have the reciprocity issues of most emulsions. No issue up to 120 seconds, 1/2 stop after that-

Thank you to all for the help.
