Photo Forum / Film Photography / Medium format / September 2004oops. Overexposed VC 160
I know this topic comes up all the time: Due to an error in how I used my light meter, I exposed Portra VC 160 at 12 EV values for a particular scene. Incident reading _should_ have been 14 and my highlights were 17. Hence my shots are 2-stops overexposed, and the highlights are 5 stops over. Should I instruct the lab on a 2-stop pull or just see what happens? I have a feeling my highlights are blown for sure... Yes, this should be pulled. VC is a "hot" film in regular EV's so a 2 stop over EV would most likely blow it out. Unless you shot on a dark overcast day. I personally would only use the VC emulsions on overcast low ley days. (Rainy days especially). Personally, I prefer the NC emulsions, better tonality, lower contrast, wider latitude. I say pull it, its your only hope of getting a decent neg from 2 stops over.

They'll pull about two frames, process and you can judge the exposure. Tony > Yes, this should be pulled. VC is a "hot" film in regular EV's so a 2 stop > over EV would most likely blow it out.

Just overexpose another film and let them test that. Apply the resulting processing compensation to the original too, and you do not lose a single frame. Film is cheap, right? What we have to do to get a certain thing on film rarely is. ;-) > I know this topic comes up all the time: > [quoted text clipped - 5 lines] > Should I instruct the lab on a 2-stop pull or just see what happens? I > have a feeling my highlights are blown for sure... The Portra films usually will give a workable negative plus or minus 2 stops. But since you are using the VC (higher contrast) type, and you say your highlights are +5... If your situation allows, I'd say attempt to duplicate the error with another roll, have it processed normally, and see if you can live with it. You also might want to shot two rolls, and have the lab pull one of them, to see whether you can live with those results. I also say shoot another roll, similarly over exposed and see how it processes and prints normally. I have seen some weird color problems when C-41 films are pulled. It's like the color layers don't develop evenly. Jon |
