Help. I can't believe I did this. But, I did it.
I was looking for my single roll of Neopan 1600 to do some night shots the other day and discovered that it was in the refrigerator marked as shot and awaiting processing. What gave me pause (I'm a pretty calm guy, so I didn't freak out) was that I'd marked it as shot at 320!

The obvious question is: how do I process this mess? I am using HC-110. Does anyone have experience having shot a roll having overexposed film by 2+ stops? Is there any way to salvage usable images here?
 
I normally shoot it at 1000 and develop in Diafine. Were your scenes fairly contrasty? If so you should be fine if you just pull your times by about 30-40% with the HC-110.
 
no worries. Most people would say the true speed of Neopan 1600 is ISO 800, so effectively you are only pulling it 1-stop. I have done this once as testing, and the results @ 320 look okay, but I prefer to shoot this at high ISO.

HC-110 might not be a safe solution in this case, since dilution B would give you too short of development time and might cause uneven development. Massive Development Chart doesn't list a time for ISO 320 with neither dilution B or H. If XTOL is available to you, I would recommend XTOL 1:2, 20C, 7.75 min. If you prefer liquid developer, my choice would be Ilfotec DD-X 1:9, 20C, 5.5 min.
 
How about shooting the 1600 Neopan at 100 ISO? It just happended to me, I wonder if the roll is a total loss..

Probably not a total loss, but some highlight details for sure. Someone even tried it with Kodak D-23 and FX-19 developers and listed the time in MDC.
