photos by mike hollingshead in oklahoma of mammatus clouds, which are formed when air laden with big water droplets is carried to the top of a thunderstorm cloud whose altitude is cold enough to freeze the water droplets. the resulting crystals sink back down towards the earth, collecting at the base of the cloud before they have time to evaporate. mammatus clouds are usually only stable for a few minutes.

Artist Thierry Cohen photographs the world’s major cities, seeking out views that resonate for him and noting the precise time, angle, and latitude and longitude of his exposure.
In Thierry Cohen’s series, Darkened Cities, we think we see bright night skies over cities. Very traditional, very poetical. Actually, what we’re seeing is the opposite. These skies are an indictment and a lament. These are the skies that we don’t see. They are also extremely clever photography, in which highly skilled execution provides rich layers of meaning.
This is a very powerful treatment. It is laborious in the extreme. To find places with the right degree of atmospheric clarity, Cohen has to go – always on the latitudes of our cities – into the wild places of the earth, the Atacama, the Mojave, the northern wastes of Mongolia. Who among us beyond a handful of professional astronomers would know if Cohen cut the odd corner by finding a good sky not quite so remote? But photography has always had a very tight relationship to reality. A good sky is not the right sky. And the right sky in each case has a huge emotional effect.
