Ilford Delta 3200 exposed at ISO 100?

I mistakenly exposed a roll of Delta 3200 in my Pentax P30T, which

apparently cannot recognize film speeds beyond 1600. The Pentax rep

tells me he thinks the film was exposed at 100 since the camera

couldn't recognize the DX code.

 

Anyway, would there be any way of salvaging this film, and if so what

should I tell the lab?

 

Thanks,

What do you think? Were your shutter speeds and apertures that the meter was calling for indicative of what you usually see with 100 ISO film in similar lighting situations?

I shot most of the roll in program mode, as I recall--it was end of a long evening and I had gotten plenty of film with another camera, so just shot the roll of 3200 on a whim. Not good, I know. I think by that point in the evening I was wearing down.

Put a roll of 3200 in the camera and see what the camera thinks the ISO should be.

 

As for whether you can save it or not, I have no idea!

You could always take it to a pro lab and have them do a clip test and see at what speed you shot the film.

The cip test is a good idea, as is checking the deafult ISO in your camera with the 3200 cannister.

 

Also, in my experience Delta 3200 can be shot from 400 on up. I have found the real film speed to be about 1000 or even 800 in reality. What developer(s) do you have at your disposal? I would try Xtol 1:1 at 68 degress for about 6 minutes, or DD-X 1:4 for 6 mintes to get down to 400 ISO. Then you are only roughly 2 stops over. I have found that Delta 3200 likes to be shot in my cameras at 1000, and I process accordingly. Shooting it at 100 is not a killer after all, just be careful with the processing.

 

Good Luck!

Your answers are very helpful. I will try the film in the camera test first, which should tell me what I need to know. Unfortunately, this particular camera doesn't display the ISO setting anywhere--it sets it and you can't override it (unless you mess with the DX markings on the canister or the DX sensors in the camera). But it should be easy enough to test another roll and then the 3200 to see what shutter speeds it recommends on Av.
