On one of the seven hills surrounding Cincinnati, Ohio, USA in summer in the mid 1970s, the air inversion sitting over the city kept the smog level high for a number of days. What was close was sharp and with good contrast, but as the distance increased so did the fog until the visibility was lost in the haze.
Taken with a Hasselblad 500C using a 150mm Zeiss Sonnar, on Kodak Tri-x 120 panchromatic black and white film. The sepia wash was used to convey my memory of the view.
Fell free to download, just give me photo credit. In my gallery is another example from a different camera point of view, and others will follow in the coming months.
