thanks for all your replies !
I developed the roll today at 3200. I didn't have a chance to make some contacts yet, but judging from the negatives, they tend to loose quiet some detail in the shadows(like you guys said).
So this brings me to the next question, if I shoot another 3200 and expose it as an 1600, should I then develop it as an 3200 or 1600 ? Because if you would do the latter, wouldnt you be overexposing +2 stops ?
