Thanks for the idea. I know with negative process all those things affect the way Rodinal works. More dilution = lower contrast., higher strength = more contrast. Here we were using 1:15 as per your suggestion and that so i guess that could be increased to 1:7, for example.
Still, as another test this evening I jumped in with both feet. Everything I read about reversal says use paper developer for it's more energetic nature, especially with lower contrast films like Tri-X. So I had just read the Ilford sheets on the subject and saw they recommended PQ at 1:5, 10 minutes. That's double the strength of using it for print and 3 times the strength of normal film processing. So I tried it at the suggested dilution and time.
The difference was dramatic and the proof is in the pudding. I think this digital photo of the strip taken from the lightbox has crunched the blacks a bit as, seen with the eye, there is still enough detail in there but the overall contrast and bite is a dramatic improvement. In my case the extra vigour of the paper dev has worked.
I think I could try a drop of sodium thiosulphite in the developer next to see if the hilights can be expanded a little more, too.
Very happy with the new test. Tomorrow I will scan the strips to get a better look and a sense of what a Super 8 sized crop will look like in terms of grain and detail.
Ilford PQ. 1:5, 10 minutes 1st and 5 minutes 2nd.
I think this single frame macro close up digital photo shows how lovely this slide looks:
