MassiveDev, Rodinal, HP5+ Confusion

[raduray]

Film rangefinder on the way and I'm studying up on how to develop film. Shooting HP5+ and decided to start with Rodinal. But I'm confused by the Massive Dev chart. It shows the same development time of six minutes for ISO 100 as for ISO 400 at the 1+25 dilution. I had assumed that pulling (ISO 400) would require less time. Pushing to 800 does increase the time to eight minutes.

That is the issue with the Massive Dev Chart...it's user created, so you have to assume that if something doesn't make sense, it's probably "wrong." I'd use the 1:50 time for an EI of 100. 9 minutes makes sense.

HP5 in Rodinal will give you a grainy but nice look
I shot many rolls at 200 and developed at 1+25

The Massive Development Chart has so many problems who would know where to start fixing it.

Use Ilford’s times:

Did you use the 4:45 time for rolls shot at 200?

This was almost 20yrs ago, my notes say 6 min @20C (agitating only once per minute)

I do HP5 rated at EI 400 in HC-110 diluted 1:49 for 10 min @ 68-72°F. I drop that to 8-8.5 min for EI 200; haven't pushed it at all.

I haven't used Rodinal in 40 years so can't help with that developer...

Especially when starting out with developing, I suggest sticking with the film maker’s datasheet. They know what they’re doing.
Speaking of Ilford, in your studies have you encountered their film rinsing method? If not, it’s worth a look.

Yes, thank you. This is the rinsing method I'm planning on.
