Overcast days are perfect for street photography, on those days light is smooth and casts no hard shadows, so you can manually adjust exposure once and just shoot.
I shot the following series in Laguna Beach on such a day. It was precisely because it was overcast and there were virtually no women wearing bikinis and such, that I felt the area to be “safe” enough to do some street photography –that means, taking pictures of people—.
The black and white processing was also a conscious election, picture control was set to B&W in my cameras even though I was shooting in RAW+JPG (in case I liked an image better in color).
This last picture was taken half an hour after dusk approximately. X100 on tripod, maximum aperture of f/16 and a exposure of several seconds. I focused way too far and the immediate foreground is slightly blurry. I plan to do a different, wider take as soon as I receive the Olympus OM-D EM-5. I already got the Oly 24mm f/2 but the camera is in such high demand I probably won’t be able to get my paws on it until the end of May.
