Fujichrome Velvia 50, OM-2, 135mm macro belows lens, telescopic auto tube, 8 minutes at f/45, tripod.
"This represents the longest exposure I've ever used to obtain a nature image. I found these spiderworts deep in a forest on an overcast day. I was trying out an old OM-2, which has the ability to autoexpose indefinitely (or until the batteries go dead). I was just about to give up on the frame when the shutter clicked off."
