I just found this photograph, which I shot a few days before my trip to San Diego and then forgot. The morning's fog was clearing as the sun glanced off a downtown building.
It was shot in color and converted to black and white in Photoshop. I tried using a program called FilmPack 4, which I had downloaded in a 30 day free trial form. FilmPack, which can emulate dozens of both color and black and white films, is interesting and I will experiment with it more. But I was able to accomplish what I wanted with photoshop.
There is no fog these days, only heat humidity and afternoon thunderstoms.
