wrong iso?

[brittanyphoto]

I work at the school store at the school i attend (Antonelli Institute) and a girl came in and shot her portraits at the iso 1600 instead of 400. I'm pretty sure i was told a way or shown a website on how to fix this but i can't remember. Is there a way to fix it in the developing room, and if so, how?

Which film? What developers are available to you?

Check the massive dev chart -- example: Neopan 400 exposed at 1600 can be developed using XTOL 1+2 for 17 minutes, or stock Microphen for 8.5 minutes.

Just follow the dev times on that chart.

Here's the link.

it was illford hp5+ and it's being developed with sprint developer.

Well, if you want to use that developer, it's not in the massive dev chart, so you'd have to use some kind of rule of thumb, e.g., 2 minutes of ADDITIONAL dev time for each stop of underexposure. CAVEAT: this is a guideline, NOT a rule.

Or you can just go buy Microphen or XTOL and develop according to the Massive Dev chart

Sprint is very similar to Kodak D76

you could pretend it's d76, you could also find more info on the sprint website, google sprint systems of photography

That is a D76 klowne
I would guess yes, the pics are slavageable, and I would recommend that she uses about 2X the time for 400.
Tell her to go easy on the agitation and to say a prayer.

The results will be interesting to say the least, grainy but with "character"
