Need some advice with developing a bastardized roll

[GKR1]

Hi Guys, went out shooting with my son and he wanted to carry the camera between shots.

Anyhow, he was playing around with ASA/ISO knob and I did not notice this until the last few shots. lol

So, the film is Acros 100 and I believe I was shooting this film anywhere from 100 to 800 ASA.

My question is how should I go about developing this roll. Should I do Stand or semi stand?

I've Rodinal and HC110 that I can use.

Thanks

Unfortunately and you may already have researched this, there appears to be very few developers for which there are any times for Acros at other than box speed. That's the bad news.

The good news is: I have the Carson Graves book called The Zone Sytem for 35mm Photographers in which he shows examples of a 400 box speed film at EI's up to 1600 so twice box speed and the negs and prints from the EI of 1600 negs still looked pretty good.

Secondly I seem to recall Les McLean mentioning developing D3200 at 25000 so 3 times box speed in Rodinal which is the equivalent of Acros at 800 and without either semi-stand or stand development.

Best of luck.

On page 58 of Creative Black and White Photography, Les McLean describes what he calls the "Dilute Developer/Fast Film" method. It involved exposing frames of the same roll of 400 speed film at IE 400, 800, and 1600.Then he writes, "dilute Kodak D76 at 1 to 30 instead of the normal 1 to 1 or 1 to 3, pour in the tank and agitate by inversion for 5 minutes. Place the developing tank in a water bath at 24 c and leave for 6 hours without agitation, then fix and wash as normal. The negatives will show good sharp grain and will print beautifully."

I have no idea if this will work in your situation but you may wish to try it.

Sounds like stand development to me, except with D-76 (which can cause bromide drag) rather than Rodinal (which can't). I tried semi-stand dev on some microfilm using ID-11 1+19 (before I got hold of Rodinal). Ended up with awful bromide drag across the bottom of the film. It was pretty quick to occur too; I agitated every 15m and developed for an hour and ended up with 4 bands of bromide drag across the bottom (each time I agitated, it stirred up the bromide and sped up development, producing more bromide, so when it settled again it was a wider band. If you don't agitate at all for 6h I imagine it would build up slowly, leading to a gradient in how developed it gets.

This may not be exactly what you're looking for, but I recall reading an article a while ago about Caffenol-C and how the author was able to get very good detail out of Acros at everything from box speed to iso 1600! Seems like it would fit your needs perfectly, as he had only one process for any of the speeds.

Thank you Gents.

I'll do more resarch and I'll try to post results on the method I used. Perhaps, it can help someone else.
