Medium format and swizzle stick

[Gerry M]

I just recently got a 127 tlr and am wondering what the best, most reliable method is for developing film. Especially so since it is ~$12/roll! I have an Anscomatic daylight tank that cannot be inverted, so swizzle stick is the only choice for agitation. My main question is: What is the proper method for agitation. For my first (and only roll, so far), I agitated with figure 8 movement for the first 30 sec and then "swizzled" for 2 revolutions in both directions every 20 sec for the remaining time. The negatives were a bit dark (over processed?). Any input is appreciated.

Don't the plastic reels for Paterson tanks compress to 127 film width?

That is a lot of agitation.

I would agitate gently and alternate - gentle figure 8 movement for the first thirty seconds then thirty seconds later gentle swizzle for five seconds, then thirty seconds later gentle figure 8 for 5 seconds etc., etc.

The proper agitation is whatever works for you. If the negs were a bit dark in your previous attempt, reduce the amount of agitation a bit. (20-30%)

My AP branded Paterson "clone" reels do.

Thomas B,
I got rid of my Patterson tanks when I switched to JOBO and they have no setting for 127.

Matt K,
It seemed at the time that I was a bit too enthusiastic! I'll try your suggestion.

frank,
I understand your point of view. Because of film cost, I am trying to keep experimenting to a minimum. More than likely, this 127 venture will turn out to be a lark and short lived. Even so, I was pleased with the outcome with the 44LM.

Don't throw away the backing paper as it will be needed if you ever want to cut down 120 rolls to 127 in future. A couple of razor-blades and some scrap wood will make an adequate film slitter.

Good thought. Thanks!
