Need dev time for HP5+ in HC-110 @ 100 ISO

[javimm]

Hi.

My father forgot to change the ISO dial on his Bessa R2M after shooting a roll of Reala and then loaded a roll of HP5+. So I ended up with a roll of HP5+ shot at 100 ISO that I have to develop .

I only use HC-110. According to the massive development chart, 6.5 mins dil H, 21ºC should do it.

Does anybody have any recommendations for developing this roll?.

I usually develop HP5+ shot at 400 ISO with 5 mins, dil B as Ilford recommends.

Thanks.

Give the Massive Chart's numbers a go, I'd say. That's what I always use for a starting point.

A long while ago I shot a roll of FP4+ with a lens that had a sticky diaphragm on a sunny day. Meaning: All pictures were severly overexposed. FP4+ and HP5+ can take massive amounts of overexposure so the negs were still very usable.

If the massive dev chart has a solution for you, use it. HP5+ is so forgiving the negs will be fine even when you do standard processing.

I would develop normally and just change exposure times when printing, but I'm sure the Massive Dev Chart way works too, it's never been wrong for me.

I've just developed the roll and came out great!!. A bit less contrasty than the ISO 400 HP5+ rolls I normally develop, which is good. Negs seem to have a greater tonal range than usual. I have to research dil H more, as I know one of its side effects is the extended tonal range although it increases grain.

I'll see when I scan the negs.

Thanks all.
