I got my first bottle of Rodinal yesterday. I've been wanting to give my pinhole camera some usage and make sure my exposure charts were somewhat accurate. This made me feel it was time to compare the differences between Ilford ID-11 and Agfa Rodinal.. Now, my testing procedures arent that strict and this was my first attempt at anything like this, so I would have to say this thread is more about wondering if my results are consistant with other peoples... Both images were shot on Ilford HP5+ rated at 400. 4x5 sheet film, developed in a small tank. Both images were exposed for 7minutes 43seconds in the pinhole camera, with an f/stop about 345.. The ID-11 was 1+1 at 20C for 14 minutes 30 seconds. Inversion agitation for the first 30 seconds, for 5 seconds (3 inversions) at the 1 minute mark and then for 5 seconds (3 inversions) each minute thereafter. Rodinal was diluted 1+50 at 20C devevloped for 14minutes. Inversion agitation for the first 30 seconds, one inversion at the 1 minute mark and then 1 agitation every 30 seconds thereafter. water stop bath, 30 seconds, Ilford Rapid Fix 1+9 for 4 minutes. both images were contact printed onto Ilford MGIV RC Glossy without a contrast filter on an Aristo V54 cold light head at the same time on the same sheet of paper for about 7 seconds at f/11 I used a Kodak gray card to judge exposure, its in the photo as well, the white square is the reverse side of a Kodak gray card, 90% reflectance The top image of the attachment is developed in Rodinal, the bottom image in ID-11... It seems to me the Rodinal has whiter whites, and blacker blacks than the ID-11 while keeping the mid tones the same as the id-11, this seems to be backed up by the histogram in photoshop, both images had the same result when measuring the grey card with the histogram... a median of '109' What does everyone think of this? Are my results consistant with everyones own experience?
