rodinal1+25 vs rodinal1+50

[david j.lee]

i am doing some macro work with apx100. i normally use rodinal1+25 with

this film, but i`ve heard that 1+50 is better/diferent. can someone with

experience on this matter give me a few pointers?

thanks.

I've no experience with macro but I used to work a bit with APX100 & Rodinal (35mm only). I love the 1:100 dilution for its sharp look, well controlled contrast/great tonality, but hate the 1:50 one because of the more pronounced and unpleasant grain structure (at least to my eyes).<br>

Never tried 1:25 though... I guess switching to 1:50 will give you less contrasty negs but I can't say anything about the grain/sharpness difference you may look after.

I've been doing my APX 100 (awesome film) lately at 1+25 for 8 minutes and the negs are beautiful.

 

I've done 1+50 and thought things were good but 1+25 is better.

David B, wich kind of enlarger dou you use? 8 minutes at 20?C?

Thanks

I believe that the 1+50 negatives are a little easier to print (Leica V-35), and there is a slight compensating effect in the highlights.

I've tested 1+25 and 1+50 on PanF @50 and Kodak HIE @320

and 1+50 will produce sharper negatives for more or less

the same grain structure. Agitation is a key factor here

so you'll have to experiment a bit.
