Three Lamps, Savannah, GA - 2015
(Click on photo to enlarge.)
This is the kind of detail shot that is best made on days with overcast skies. If this had been a bright, sunny day, this photo would have been almost impossible to make. The wall would have been so bright that it would have lost the subtlety of it's coral color. If we expose for the wall, the inside of the arches becomes a black void. The flames of the lamps are likely almost invisible in either case.
So when the skies are ugly, concentrate on the details and leave the sky out of your photos. Take advantage of that beautiful, soft, even light that cloudy days provide to bring out the details in the details.
