Response to Rodinal Stock Solution

from Nigel Smith (nlandgl@unite.com.au)
from the weird and wonderful (but not recommended by me) I recently read somewhere about 1:400 and 1:800 dilutions with Rodinal.. so thought I'd try it! I used 0.75ml (as acurately as I could measure it in a 2 or 3ml suringe) in 300ml of water for a TEST roll of FP4+ which was exposed at 200asa (as indicated by my source) I developed for 100mins (was meant to be 90mins but I forgot about it!) with agitation at the 1,2,5,10,20,30,45 minute marks (no agitation in the last half of development, as recommended by the source) To have something to judge against, I also shot the same subjects on another roll of FP4+ (bulk loading is good for somethings) and processed at 1:100. I haven't had a chance to make some prints, but the 1:400 negs look ok, a bit thin (which indicates 200asa wasn't suitable, the 1:100 ones were thin too) Scans using a flatbed with transparency adaptor (1600dpi) didn't show much difference, and what differences I thought I could pick might have been my imagination. What has this proven.. probably not much! :) Going to try the 1:800 dilution one night (yes that's the recommended development time.. overnight!) just for the hell of it!
