Everyone seems to do stand development at 20c, but many say the temp doesn't matter much. I don't have AC, and it's about 80F in my apartment. My tap water is about 25c. Should I try to cool it down with ice, or is that an acceptable temp?

I'm using agfa rodinal and TF4 fixer, developing arista.edu ultra 100 120 film. This is my first time developing film.
 
A roll that i developed in 22c came out with more noticeable grain.
Here is a pic.

Edit: I didn't do stand developing though...
 
What film are you going to use? Not all films feel comfy in a 25 degC soup for too long. There will be so much grain that the resolution of the film will be considerably and very very notably reduced.

I start from 20 degC then put it in the fridge.I am not sure this film is suitable for stand dev.

I think it will be all right. I picked it based on results of stand development from here: http://filmdev.org/recipe/show/9638.

But I guess 25C might add too much grain.

I imagine the temps drop significantly in the fridge if you're doing stand. What does that do to the results?

Thanks for that insight. I'm going to get a cooler and put the bath with ice inside there and develop with the lid on. I have a temperature probe on a long wire that I can put in there to monitor temps from outside and have it beep when it gets above 20C.

Then DON'T piddle around with stand development. There is a good reason why conventional agitation became the standard. What advantages do you think you will get from stand development? And how will you know what they are, unless you already have some experience of normal development?

(Semi-) Stand dev? I do not care about temp to be honest .. I leave it on really hot days but I do not care if it's 18°C or 27°C
The theory is that you soup the film for so long in so low concentration that the activity of the developer gets veeeery low .. so I conclude it doesn't matter if it almost(!) stops after 18 or 26 minutes when you leave it standing for one or two hours

Mostly interested in it because it's a slower process that is easier for me to follow, and really hard to mess up. I feel like as a first timer, this is a good choice. Then later when I get used to handling film and chemicals and tank, I can piddle around with conventional agitation.

Edit:
This thread is actually a good example of what I mean. Someone above showed some pretty unacceptable grain due to temps that were 22C using normal agitation. Meanwhile someone else using stand development seems to get by just fine at 27C. The whole process just seems more robust to me.
 
I enjoy using stand development, especially wih 100 ASA films and slower.

However, it seems like the time it takes can be a deterrent to some folks, even me when I want to get it done rather quickly, then I use something like D-76 where I usually dilute it 1+1. I find that stand development with Rodinal or some other name works best for me for developing 35mm with 6 ml of stock to 600 ml of water then develop for 1 hour. I try to keep it at around 68 to 70 degrees f.

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!

Very true. I get what you're trying to say. It's good advice. Just, for me, I'm just trying to see: can I make pictures come out on film for now. I'm an absolute klutz in the kitchen, so following all the steps properly is just intimidating for me.

Next I will try standard development!
