Rodinal Stand Develop Color & B&W

[OptiKen]

I've been seeing a lot of posts lately regarding stand developing with Rodinal 1:100 and am ready for an experiment.

I have a 126 Instamatic Cartridge with C41 film in it and a roll of Arista EDU 400 120. I am thinking about putting both rolls in the tank with the recommended amount to cover (in this case, 790ml) of Rodinal 1:100 and doing a one hour stand development process.

It had already been established that I'm crazy, so my remaining question is, "will this work or should I start thinking elsewhere"?

Thanks
Ken

I've stand developed in Rodinal 1:100 for an hour several times, the only problem I had was that I felt that I lost some sharpness. Ever since then I've been using Rodinal 1:50 with normal times and normal agitation. That being said no reason that what your planning wouldn't work, other than your C41 obviously won't come out as color it will be B&W.

Using Rodinal at 1:100 will result in loss of contrast and film speed. As has been said MANY times before stand development is not a general purpose development method. It's only valid use is to lower contrast from an unusually contrasty scene. Most books on the Zone Method will explain its use.

So far I have developed 2 rolls using the stand method at 1:100 and was pleased with the results. But do want to use 1:50 with normal times and normal agitation to compare results.

I've found a gain in speed in some films from an hour stand in Rodinal 1+100, and can also confirm a loss of sharpness, I also disagree that it's only for lowering contrast of high contrast subjects. Yes it will work, but your colour film will be in b&w unless you rehal process it. I've also found a few of my 1+100 1 hour stand negs too contrasty to print on grade 0, and had to be printed at higher grades with split-grade printing and selective latent image bleaching to get a decent print in the dark room.

Test completed and...failed.
I went to the massive development chart and it said to develop for 2 hrs (I stuck with 1 hr as planned) and to rotate for the first minute (I did 30 sec) and to rotate for 10 seconds every minute (I didn't - I did 3 rotations at 30 min).

The black and white negatives came out extremely thin (underexposed or underdeveloped - my vote is for underdeveloped) and the old roll of 126 color film I found in a camera did not develop at all.

Time for more practice and experimentation.
I had to really work with the histogram to get to this point. I don't really understand the line in the pic (dark on the bottom). The film was stacked in the tank with the 126 on the bottom and this 120 on top of it so I really don't think it was standing in developer that did that. Maybe a shadow? I don't see it on the others but haven't looked closely at them yet
