hello all, just thought i would seek the opinions of those more technically proficient than myself... a few months ago by mistake i found that Ilford HP5+ could be pushed from ISO 400 to ISO 3200 using Kodak T-Max developer at 75 degrees farenheit for 9.5minutes... as for why i was trying to push the film, i was in a tight situation and needed 3200 and i knew i had a better chance with the HP5 than nothing at all... anyway, i have used this several times since, and it has had pleasing results...i would say the grain is similar to if not better than T-Max 3200...that and i've never been the biggest fan of kodak... recently however, i have grown weary of buying T-Max, and wasn't to keen on the photographer's formulary t-max substitute and was looking for something that was economical for me (a lowly photography student with a very limited budget) and i had heard of PMK Pyro, saw the dilutions, and was stuck today, testing films i shot three rolls of HP5+ at ISO 3200, i then stepped into the darkroom, estimated that i would need somewhere between a 45%-75% time increase in development and went with 3 times, 12+45%time = 17.4mins (a fellow student disturbed my train of thought and roll was wrecked) 12min+60% time =19.2mins, this roll came out wonderfully...its contrast was good (to my own eye at least) and the density was good...then i did the 3rd roll at 21mins (75% time increase)...this came out thinner than 19.2mins....(btw this was all done at 22 degrees celsius) at the moment i have no clue what went wrong...i'm hoping my first success wasn't a fluke...and that the time (19.2mins) i found is good and somewhat repeatable...the only thing that I can remember is not agitating as consistently as I did with the previous roll... any suggestions, opinions, etc would be appreciated, and for those who think i'm crazy...i like grain (not to mention i print most of this with lith developer anyway) thanks
