Perhaps you guys can help me, I'm looking for a temperature chart going beyond 24°C, because actually we have around 28-30°C.
or is there a simple formula?
The first roll worked well by guesstimate, maybe I was just lucky _________________

This one goes to 27 degrees. http://www.ilfordphoto.com/Webfiles/2006210208211880.pdf
Would it not be easier to just develope at a lower temperature by chilling in some cold water? _________________ Casual attendance these days |

I would love to be able to complain that the cold water is 25 degrees. It's getting difficult to remember when the outside temperature here was over 25 degrees. Global warming? MEH!

Ice in a bucket may be the answer during the warmer months, or just move your darkroom to the UK. _________________ Casual attendance these days |

Errm, no!
It's never perfect.
Ice in a bucket sounds good, I'll try that. Sounds better than chemicals in the fridge, which might give some troubles here... _________________

Here's a chart from the Ilford site for temperatures up to 27°. Maybe you could extrapolate if you need higher.

Thanks friends!
I'll give it a try, I need to finish the next roll first.
The film was the Ilford Pan F PLus with developed with Tetenal Ultrafin at 1+10, which is rated at 3min @ 21°C.
Developing time was 2:20.
Next time i'll try a 1+20 dilution, to get more comfortable times. _________________
