ILFORD DELTA 3200 Dear Sir In the past I had problems exposing Ilford Delta 3200 at the given 3200 ISO rating. My pictures always came out dark. Someone told me to rate it at 800 and recently I saw in Popular Photography Magazine that they rate it at 1250. I recently shot a roll rated at 1250, but now I am not sure what the lab will do. Will they rate it at 3200 or should I tell them to develop the prints as if for ISO 1250? I need some help. Thanks Pieter Roelofse

Exposure and developing information here: http://www.ilford.com/html/us_english/pdf/delta3200.pdf Are you doing the developing yourself or sending it to a lab? If to a lab, are you giving them any instructions? In the link above, Ilford states: "DELTA 3200 Professional has an ISO speed rating of ISO 1000/31º (1000ASA, 31DIN) to daylight. The ISO speed rating was measured using ILFORD ID-11 developer at 20°C/68ºF ..." It's possible that unless you tell the lab to develop for ISO 3200, they will develop it for ISO 1000 instead, a 1 2/3 stop underdevelopment. The situation is similar for Kodak T-Max P3200, which is also nominally ISO 1000.

I never had problems doing Tmax 3200 at 3200. Not saying very much for Ilford if their 3200 has to be done at 1000.

I have not used Ilfords 3200 Delta, But have quite a bit of experience with T MAX 3200. I was under the impression that they both use a t-grain and are very comparable. I have always developed my own black and white film. You should definately talk to the lab you use. I would go so far as to talk to the person who is doing the processing. if he does not have information or suggestions on the best ISO for them to develop (or gives you a puzzled look), I would look for a different lab. These High Speed films are very versatile(I know the T-MAX is for sure)as well as expensive as far as B&W film goes. It can be painfull to get your film/prints back when they do not meet your expectations. _______Matt
