HP5 development questions

DennisGrieder · Mar 31, 2010

i looked up a guide on developing the HP5 film, i understand most of it, but i need a-little help with some terms they're using:

At Meter Setting:
EI 400/27 ILFOTEC HC (1+31) ID-11 (Stock)
EI 800/30 ILFOTEC HC (1+31) ID-11 (Stock)
EI 1600/33 ILFOTEC HC (1+15) MICROPHEN (Stock)
EI 3200/36 ILFOTEC HC (1+15) MICROPHEN (Stock)
Finest Grain ILFOTEC HC (1+15) PERCEPTOL
Maximum Sharpness ILFOSOL-S (1+9) ID-11 (1+3)
Maximum Film Speed ILFOTEC HC (1+15) MICROPHEN (Stock)
One-Shot Convenience ILFOSOL-S (1+14) ID-11 (1+3)
ILFOTEC HC-D MICROPHEN (1+3)
Economy ILFOTEC HC ID-11 (1+3)
ILFOTEC HC-D MICROPHEN (1+3)
Rapid Processing ILFOTEC HC (1+15)
Replenishable ILFOTEC HC

to my understanding the number before the forward slash represents the iso/film speed correct? I cant figure out what the number after the forward slash means.

Any help/advice is appreciated.
Thanks

It's the DIN - http://en.wikipedia.org/wiki/Film_speed#Current_ISO_system

so i don't need to pay any special attention to the second number?

No, it is just a different way of stating the film speed.

Never feel bad for asking any question, even if the answer is obvious. You just may be helping someone else who is too shy to ask for themselves, and truly need help.
