Re: [APML]: Hypering PJM (was: Best Beginner Film)
Well, until I get a chance to try out unhypered PJM-2 on those 2 and 3 hour
photos I will keep hypering it. With the scarcity of clear nights in these
parts I don't get the luxury of being able to do much experimentation! :-)
I hyper PJM-2 for 7.5 hours using Jerry's standard technique. But beware -
your mileage is almost guaranteed to vary! The only way to get the time
right is to test various times until the density comes out close to 0.1
over base. It's better to be a little under than over hypered.
