Beutler development times
I am looking to use developers with more acutance than Rodinal and will
mix up some Beutler to the original formula. Can anyone reliably advise on times (and dilutions?) with HP5, Tri-X and FP4 ( all in both roll and sheet). Thanks very much. |

In any event, Paterson Acutol will perform much better on those films than Beutler will, because Beutler developers compress mid-tones. |

I used 1/2 of the full liter to develop a 120 Pan F using a 1 liter tank. If you have the FX-1 formula at hand you will see that 1/2 of a liter of Beutler is 1 liter of low sulfite FX-1. I tried both and found that 1/2 liter of the low sulfite FX-1 was more suited to Pan F. HP5 and Tri-X may need the more metol Beutler. I've not my records at hand but usually shoot for 9 minutes or more. Use an over size tank if possible and vigorously agitate seldom. I liked the results and plan to do a lot more work with the Beutler/ FX-1 types. I think the two are becoming more popular. Photo. Formulary and now Barry Thorton have the ready-mix. R. Suzuki thinks it great. He has several variations. I think you can find his article by searching Google for, fx 1 . Dan |

Dan No times for Beutler here but with FX-1 a good starting point for HP5+ and Tri-X would be 20 minutes. T-Max 400 takes about 13 minutes. Tobias |
