No Wind

As is evidenced by the drooping wind-sock on top of the big condenser (or whatever it is). No doubt a contributing factor in the fog that rolled-in later on.

This actually reminds me of a photo that I might have taken back in the '80s - except for the fact that I would never have been able to get this much detail! Maybe with some fine-grained Ilford FP4 and a tripod but certainly not hand-held.

(I couldn't use my tripod tonight because the reason I was there was to shoot a time-lapse video with a new app on my phone and the tripod was being used for that!)
