Sounds like great fun...here at the school, all we have access to is D-76 powder and TMAX professional concentrate...could anybody recommend a similar strategy with these products?

Well, when we were kids, we used to develop old Tri-X (ASA 400) in Rodinal straight at 95 deg F for about 15 minutes. This produced somewhere about ASA 8000. That's a little better than 4 stops. Lots 'o grain and three shades (black, gray & white.) By accident, some images were quite haunting.

I was talking to an old parish priest last night who taught, among a mountain of other things, photography in Nigeria for about 27 years.  I told me about this developer called "Promicron" and extended development that allowed for candid photographs in extreme low-light conditions at 1/125 that produced fantastic results.  He said that he even used candle light as a source.  What modern techniques are available for such devious activity?
