Rollo Pyro and 4x5 Delta 100 times

I did a search on Digitaltruth website for times using 4x5 Delta 100 film. I use two developers, Xtol and Rollo Pyro on a Jobo constant rotary tank that seats on a Beseller motor. My previous experience with Rollo Pyro is with Efke100 film and for that I used 6 minutes. The Rollo Pyro that I use uses 3 parts, A, B and C.

Digitaltruth gives me a message of "Sorry, no records were found!" I would appreciate if anyone uses the same combination and wants to share how many minutes I should use.

Thanks in advance,

Jaime.

I have Rollo Pyro, but I have not used it yet.

I was told that temperature does not matter, nor film type.

Any feedback on Rollo Pyro would be appreciated.

I have used Rollo Pyro for a number of years now, but I have only used it combining parts A & B into a single solution. I don't use Delta but a starting time maybe around 6-7 minutes based on similar films. My favorite dev. for sheet film.

Process in A for 5 minutes,
B for 6 to 7 1/2 minutes,
wash in water twice for 30 seconds,
TF4 or TF5 1:3 for 3 minutes,
wash in water twice for 30 seconds,
the same solution A for 2 minutes,
and wash for 15 to 20 minutes,
30 to 60 seconds in PhotoFlo and
hang to dry.​

Any feedback on Rollo Pyro would be appreciated.

I see, I guess I will try same times as with Efke100. I hope I have my notes around. I use 3 parts A and B come in liquid form and then another one comes in powder and I have to mix 1/8 of a tea spoon (this is the part I don't like). If I do some testing I will be posting here the results.

I did some testing with 6 minutes and the negatives came out really good. Just when I was about to start my test I decided to tape the process. I made a 10 minute video, but it is sloppy and I didn't prepare my text before hand so bear with me for mistakes etc...
