This stuff is pretty sweet. Here is it shot at 50asa, and probably a little overdeveloped. Zero post-processing. Used Tmax at 8 minutes (around 68-70 degrees). I'll probably try 7 to 7.5 minutes next time, try and bring out more gray tones. Right now the black is like... black. It looks awesome but properly processed stuff should need post-processing right?
I'm thinking a yellow filter might pull the sky into a better useful zone. Otherwise it mostly looks light.
Any thoughts?
