So last night I burned a roll of pound land 35mm in the garden taking the same shot, so that I had a roll of 35mm that I could try some timed tests in Rodinal for varying times. In the darkroom I extracted the length of film from the canister and cut it into three lengths. Each of these lengths was then loaded onto a separate spiral and then into a dev tank.
I mixed up a Rodinal solution of 1:50 and at 20 degrees started the tests one at a time. The 12 and the 13 minutes were fine but looked pretty much the same once pulled out of the tank. For this reason I added an extra thirty seconds to the 14 minute tank to try and get through and get a thinner neg.
Alright yeah I know that they’re not easy to see details but you get the idea, they all look fairly similar.
Here you go this is a scan and close up. I think that the 13 minute result is the best for overall contrast . I am slightly confused though as the 11 minute result from the other day pre-scanned like this –
I seemed like the neg was too dense for my scanner to see through, resulting in this horrible digital mess. When putting the question out there on the internet I received much the same response. I had hoped that leaving in the dev for longer would cut through some of the orange base and it would appear that this has worked. Or at least something else has worked…! Either way I appear to be able to get a workable neg out of a c-41 film in black and white chemicals.
So to recap.
13 minutes in Rodinal 1:50. Agitate for the first minute then the first ten seconds of each remaining minute after.
One minute in ILFOSTOP, agitating for the full minute.
5 minutes in Ilford Rapid Fixer, agitating for the first minute and then the first ten seconds of each remaining minute.
Ten minute wash in 20 degree (or there abouts) water.
Final wash in Kodak Photo Flo. About six dunks in a tank of solution.
Hang to dry as normal.
