Ok That was my best attempt at a catchy thread title. lol anyways down to business.
I have read probably 100 different threads on "proper agitation." I think there are about 9-10 different schools of thought. Mine is pretty simple 10-15 seconds of "gentle" agitation the first minute and then 5 seconds of the same each subsequent minute. Easy enough but here is where my question comes.
I have been reading "The Negative" and it talks about different kinds of agitation and on here people talk about what LACK of agitation does. So I decided to do a little test. On a roll of Fomapan 100 I spent taking photos of mostly low contrast subjects with two images that included some overcast skies with different shades and shapes in the clouds. Am I right in thinking that less agitation will cause some "blocking" in the highlights and PREVENT them from being over-developed thus producing more details in the clouds??
Reason I mentioned shooting a less contrasty scenes was because I also under-developed to "contract" the zones if you will. I shoot my Foma at box speed developed in Rodinal 1+75 at 7:20. I think Digital truth says 1+50 at 7 minutes. My agitation was gentle for 10 seconds then 5 seconds until the 3 min mark. Then NO agitation for 2 minutes, on the 6th min there was a swirl of the tank and then none for the remaining 1:20.
My test results wont be able to be completely looked over until the negatives are completely dry and I get a scanner to look over them more closely. I did notice that I could make out different tones in the clouds but really cant tell unless I shoot the same "scenes" with more or less agitation.
So what is it ladies and gents? Less agitation cause "blocking" giving you decent tonal range in bright scenes like clouds??
