I'm thinkg of trying D76. Afterall Efke 25 is an old formula film so it may work best with an old formula developer. :-) -- Keep working millions on welfare depend on you ------------------- |

I've seen significant contrast compression in TMY using HC-110 Dilution G (1:119 from USA syrup), 15 minutes at 70 F, and agitation reduced to every 5 minutes -- in fact, *too much* compression, even for harshly lit full-sun scenes. It should be easy to increase contrast enough to get negatives you like in your light, but the above dilution and agitation compensate enough to provide nicely pictorial contrast even with document films like Agfa Copex Rapid. -- I may be a scwewy wabbit, but I'm not going to Alcatwaz! -- E.

Fortunatly I didn't spend a whole lot of money on the developer. Even then it only cost ~$10. What effect does the very high dilution have on grain size?? -- Keep working millions on welfare depend on you ------------------- |

Speaking of Rodinal, I've found that high dilutions tend to give finer grain when used at 1:100 and 1:200 in modified stand-development. However, you are embarking on a whole new area if you use your rotary processor. I'm lost in that dimension; never tried it. Anyone here ever tried FG7 in high dilutions - for example, 1:30, 1:90? I was gifted with two fresh gallons of the stuff, along with a bottle of Edwal's sodium sulphite. |

If I were to use high dilutions of Rodinal it would require tray processing. Every now and then I consider tray processing film. The my senses come back to me and I load the film in my Jobo. :-) One of these days I will give tray processing a try. Has anyone tried using two trays with developer to develop film. The idea is that you put the film in one tray and when it's time to agitate you simply remove the film one sheet at a time and put it in the other tray. No sliding of film means no scratching. : Anyone here ever tried FG7 in high dilutions - for example, 1:30, 1:90?

While the full capacity of the tanks is large only half of the volume of the tank is used when putting it on the processor. Remember when processing the tank is horizontal and the continuous rotation of the tank assures that film is in the chemistry and properly developed. As an example the 1520 tank I use when processing roll film has a capacity of two rolls of film and 240ml of chemistry (~8US ounces). -- Keep working millions on welfare depend on you ------------------- |
