Hi all,
It seems PanF is rather a 25 or less? Anyone experience?

Is it PanF a 50ISO?

it depends on what you are using for developer. PanF+ with Rodinal at ISO 50 is quite a nice combo if you ask me. Others, such as XTOL and LC29, not so good results for me, so I'll let other relate their experiences.

Yes.
You can reduce the true ISO (ultra-fine-grain developers). You can increase it (ISO 80 or so in Microphen or DD-X). You can over-expose and under-develop it. You can get the metering wrong (e.g. incident metering). You may prefer it over-exposed. But under ISO conditions, in a normal developer, yes, it's ISO 50.

May be the indications of massive development chart are wrong.
HC110 dil B: 4 min at 20 degrees: my results are negative with no shadows details; don't know if underexposed or underdeveloped.

I use 50 ASA for Pan F Plus. Develop mostly in D-76 1+1.
Working on finishing a 35mm 36 exposure roll.

In HC110, I prefer treating it as 25. At 50 it looks a bit too contrasty to me.

Sorry but contrast is a function of developing time and not the EI at which you have rated the film.

ACtually Lawrence, 'downrating' a film -- overexposing it and underdeveloping - is a method to lower contrast. The EI used is related to the proper use of that method.

Anyone has experience with PanF and HC110 dil B? Which time?

Actually Colin it's the underdevelopment that lowers the contrast, not the overexposure. Lawrence is absolutely right. If you deliberately underdevelop your film to get less contrast, yes, it's generally a good idea to increase the exposure. But the overexposure does not itself decrease the contrast.
