A couple of quick questions that I'm hoping some of the film-buffs out there might be able to help me with - 1. I picked up some expired Kodak Ektapress 1600 - my pictures all came out super grainy. Which made me wonder if the shutter speeds were out on my OM1 (but previous film had come through AOK) or if these 'high-speed' films were not actually intended to be shot at 1600 but something slower (as implied by some googling for 1600-3200 type films). So, learned friends - whats the deal ? Should I just run another load of film through and experiment with settings to see what works best ? 2. I've read a bit about 'stop down metering' - as I've picked up an old non-AI Nikkor f1.2 55mm I'm keen to try it on my F3HP (it works fine on my E-P1 of course). On the F3HP, I flick up the AI tab and mount the lens, when I half close the shutter I get a meter reading different from when I hit the DoF preview button (stop down the lens) I get another reading (obviously at the aperture that would be used to take the picture). What do I actually do to take a picture - switch to fully manual, line up the shot, stop down the lens, get a shutter-speed reading, then press the shutter release (while still holding the DoF preview or will actuating the shutter move the aperture setting to its appropriate location ?) Thanks in advance, Raj.
