Simple Agitation Question

from Mike Foster (mike567@acgecorp.com)
Hi,

Please help me by answering this simple question in regards to agitation when processing film.

A person processes two identical rolls of film using identical developers. For the first roll (A) he agitates slightly and every minute. For the second roll (B) he agitates vigoursly and at every 20 seconds. However he reduces the total developing time for (B) so that both the rolls have identical densities.

When comparing the negatives from A and B he will notice:-

1) That A has lower contrast than B.

2) That A has higher contrast than B.

3) Both A and B are identical in terms of contrast.

Please pick 1, 2 or 3! Thank you!!!

In case you are wondering why I am asking this question, the answer is that I am desperately trying to reduce the contrast Kodak Tech Pan. I just love the grain and sharpness of this film. But the contrast is just too much!

The developer I am using to process this film is Agfa's Rodinal mixed with a solution of water and sodium sulfite. I have tried all sorts of dilutions and 1:200 is the best so far. But still too contrasty...

Thanks!
