I'm panicking - I don't know which roll was shot at a different EI!

Guys

I'm having a panic. Can you help answer my questions?

Yesterday, I shot 4 x rolls of Fuji Pro 800Z 35mm. One was shot indoors, and the other three were shot outdoors in the same light. The one indoors was shot at EI800. Two of the three taken outdoors were also shot at EI800, but one was shot at EI400. Trouble is, I can't remember which one I shot at EI400, and all 4 rolls were plonked in the same pocket!!

When I send the films to the lab, I usually tell them what EI I used for the films I send. What should I do in this case as I don't know which roll was shot at EI400? Ask them to develop on the basis of all films being shot at EI800 (seeing as that was the case for 3 out of the 4) or do I need to mention it at all? If all are developed on the basis of being shot at EI800, what is the likely impact going to be of the one shot at EI400 - will my photos be ruined? Is there likely to be a big difference regardless of whether I mention it or not?

Thanks for any help on this one.

800 exposed at 400 will likely improve things. just send them in. was this the wedding you were gearing up for?

You can tell the lab what you like but 99.9% will still process at the normal C41 time, only E6 films get pushed & pulled Sometimes C41 films get pushed 2 stops or more but it's specialist.

So what are you worrying about ?

One should not make a big difference. Two stops would make a difference. Three stops ==> Oh yeah! Now that is what you are talking about!

C-41 is a standardized process. Unless you specifically order them to push or pull, it will all be processed the same. An attentive and caring lab would likely push C-41 marked higher than the box speed, but would almost never pull C-41 marked lower. The one stop of overexposure the one roll received is well within the latitude of the film. It will be easily printable. So, drop them all off together, have them all processed the same, and you will be fine.

If you ever need special processing, do not count on notes on the film itself to do you any good. Make you you specifically order the pushes or pulls in the paperwork, not just on the film.

Sorry, I know these situations are quite stressful, but I couldn't resist.

As mentioned before, one stop isn't that much. You shouldn't panic

Put them all in together it will be fine.

Have the lab do a lead snip test.

Thanks guys - thank goodness for that.

David - Yes - it was the wedding shoot. A full write up with request for critique coming soon, once I've had the results from the lab (it's amazing how people remember individual circumstances here at APUG - very impressive).

I'm panicking - I don't know which roll was shot at a different EI!
