Old Pa Pitt often tells young photographers that there’s no such thing as correct exposure. He likes to make dogmatic pronouncements like that and watch their reactions. But this is what he means. These two pictures of the skyline at night are taken at quite different exposures (two whole stops apart, in fact). The one above is the kind of exposure you will usually see in a night shot of a city skyline. The one below is much closer to the way the skyline actually appears to the eye of the observer. Which is correct? Neither, of course. It is a matter of taste, and of creating the image you, the photographer, wish to create.
