APX100 + Rodinal: Time?

GOOGLE can find a pdf file from Agfa with their times. GOOGLE can find the Massive Development Chart with several times & temps.

Maybe Earl will be along with his time & temps.
 
and 10ml of Rodinal per roll (80 sq. in.) of film. A lot of people use a lot less than that, in the 5ml range. If you're feeling daring.
 
17 minutes seems long to me. I use 1:100, and I haven't used 1:50 for quite some time, though I may in the near future. My time for 1:100 is 20 min, so I think 17 min for 1:50 is too long, at least for the way I meter, shoot, etc.

The massive dev chart lists both 13 minutes, with 17 minutes for a push of 1/3 to 2/3 stops. If you feel uneasy about 13 minutes being too short, try 15 as a starting point.

Whatever you do, go easy on the agitation unless you need a lot of expansion/contrast boost. I use 30 seconds of initial agitation (inversion), then 3 gentle inversions every three minutes thereafter. Rodinal is very sensitive to agitation; less agitation means better grain quality.

Thanks for all your suggestions.

Developed 12.5 - 13 minutes in Rodinal 1+50, with very careful agitation every two minutes. Some of the frames came out a little thinner than I prefer, but that may be an exposure issue. I think I'll add 45-60 seconds next time.

Still, I'm pretty happy with the results. Here are a few, scanned with my Nikon Coolscan IV-ED:

Nice shots. Iceland?

I've always been happy with Rodinal 1:50 for 13 minutes at 68 degrees. I (gently) agitate for 5 seconds every minute. Five ml of Rodinal per roll has been fine. I like Trius's 1:100 result, too.
 
Jarle: Very good results!

Laura: Thanks. That shot was partially a test of the Oly 35SP's flare characteristics.
