Thanks for putting these up. I've always wanted a 'sticky' to these posts. But this is a gear and and now a digital forum, so chances are that won't happen.
Don't get me wrong I still like it here, but there are not as many posts that I'm interested in, in the last year.

You'd think the MDC would have all of this. One thing that's always irked me about the MDC is how they don't keep historical times and update existing times for newer versions of the emulsions. Doesn't help when one is shooting 10-20 year old film.

Ranchu - was there any mention of the agitation routine for these recommended times?

Ranchu, thanks for taking the time to post this info. These stuff gets harder to research each year.

I know I don't even bother with them any more.

No, I'm so sorry, that's all of it. That's clearly the missing link here, I would assume 'normal' agitation since it wasn't mentioned, but I don't know for certain. It's from here- Current 35mm Practice William L. Broecker; Editor Published by Morgan & Morgan, Inc., Dobbs Ferry, New York, 1975

I just shot, by accident, some Tmax400 at EI 50. Yikes, I reduced the development by 10% and then another 10%. Actually, the negatives didn't look to bad, (and this is Tmax). I'll post a few soon, this is my kind of post, thanks for posting this.

Not sure if this is helpful, but there is this pdf of instructions:
http://adox.de/RODINAL.pdf
You can also find a pdf of Agfa B&W chemistry instructions. It has a page or two on Rodinal. I don't remember where I got this but one version is on my website:

Where did you get those charts. The different lighting conditions development is really helpful. I wish they had this for other developers, but I suppose you could come close if you were clever. My 50 EI mistake worked out. But then they were scanned so you can cover many errors with levels and curves. Although, I didn't really have to resort to tricks:

Thanks for this. Actually I just shot a roll of APX100 today that I'm going to develop in Rodinal 1+50 tomorrow. Seems as if my usual 15 minutes for normal contrast situations correspond to these charts.
@charjohncarter: I absolutely agree - there should be more threads like this instead of at least 5 for each new rumour of the newest digital thing or the umpteenth 'I want a Leica - should I buy an M3, M6 or a new watch' threads. Your EI-50 mistake doesn't look like a mistake at all FWIW.

Thanks for the post. Interesting how light conditions and dilutions are mixed in the tables.
My last Rodinal use (Rollei Retro 100, Rodinal 1:50, 20 degrees C, 14', invert every minute, 9am in Sunny SF, at box speed) fits quite well too. See http://ferider.smugmug.com/Picture-a-Week/2013/0613-B and this as my favorite shot of that day. Not much PS leveling was needed, histogram was nice and broad.
And here for the dark tones:

I love Rodinal.

On the matter of different exposure and developing times for different lighting, I found Mike Johnston's articles on his "Not much of a System System" very informative.
For refererence I'll also link here to another thread on Rodinal development times - Rodinal Basics.

I read that once before, but I just bookmarked it to read again. Thanks for putting it up.
Also in the news. The sky has fallen: my Costco has discontinued C-41 35mm processing.
If my Algebra comes back to me I'm going to do a chart like the OP's for HC-110h. It is a linear developer, but extrapolation from the Rodinal should be close enough even though I understand that Rodinal is not a linear developer. The dilution changes are not much between usable EIs so this should work.

Those times seem rather long to me. I'm usually about 1/4 less than those numbers. Variation is normal but this makes me think I may be under developing a bit.

Chris - thanks for the link to that other thread on Rodinal (and the links within it). I had been reading it earlier. Do you know if Rodinal, or something like it, is available from a vendor in Australia?

I got my last order from Vanbar in Melbourne, a few years ago. Postage was expensive.
Yep - looks like they still have it. http://www.vanbar.com.au/catalogue/product.php?id=74766

Roland - I love both those photos - very nicely done and well presented too.
