So I did it! Looking at the negatives as they are drying, they look very good. The photos aren't very interesting, I was mainly testing a new camera that I wasn't sure worked. I've also never shot film with a fully manual camera, and haven't shot film since like 2003.
I used a cooler and tried to keep the temp lower, just because why not. I used filtered tap water and put the beaker containing rodinal and water in the ice bath (which was 15C) for a while to get it down to 20C. Meanwhile I was presoaking the film in filtered tapwater, with the tank sitting in the cooler ice bath as well. I probably presoaked it for more than 10 minutes, I didn't time time.
Then I dumped the rodinal mix into the tank and put back in the ice bath. I used 500ml:5ml mix. I did some inversions for like 30 seconds. I forgot to time that as well. At the 30 minute mark I did one inversion and did another 30 minutes.
The bath was only 15c so I left the cooler open, but then at some point my thermometer beeped because it had reached 23C. I must not have heard it when it reached 20C (oops). I put some more ice in it to cool down. I got the bath down to 17C, hoping that it would cool whats in the tank to about 20, but who knows what it was at.
When it was done I rinsed for a couple of minutes dumping the water out a few times.
I forgot to shake up the TF4 before mixing it with water (oops!), but I did shake the mixture once I did mix it. I hope that's not a problem, I dunno. I agitated the fixer 30 seconds each minute for 5 minutes.
Finally, I rinsed it for about 5 minutes, and then put some photoflo mixed 200:1 with water for 30 seconds and now it's hanging up.
All this to say: my temperature control was all over the place, I screwed up several times, and it seems to have come out all right anyhow. Thanks everyone for the advice!
