Hello,(posted 9291 days ago)I just did a simple test placing shots of some textured fabric at different shutter speeds relative to the meter reading, with 35mm APX 25 and xtol 1+2. It seems that there is a bit too much density at zone 1 and too little at z 9, although I'm not going to go to the bother of a densitometer. There is definite texture present in both those frames. Does this mean that the combo is faster than EI 25, and the dev time is too short for the temperature used?
I developed according to the Kodak data sheet, 9.25 mins + 15% (300mL@1+2 per film)(rounded to 10 mins 30 seconds), @ 20C. I notice that the times in the data sheet vary greatly with temperature. Could the lack of contrast be due to cooling of the solution during development? I am thinking of trying it at EI 32 and deving for 12 minutes next time, with some more test shots... does this sound reasonable and is it likely to ruin any other shots I have on the roll? Or would it be better to keep the tank in a water bath during development, to avoid inconsistencies dependent on air temperature?
Thanks in advance from a newbie. Sorry for asking so many questions!
