Black on black

If you've been taking pictures seriously for a few years you know that photographing a snowy landscape where everything is white will most likely be underexposed.  This happens because meters, which are programmed to read everything as 'middle gray', try to make the snow gray, thus the pictures are too dark.  The same thing is true of black on black but the opposite happens.  The meter interprets the black subject or scene as gray, thus the picture tends to be too light.  When shooting in this kind of situation, carefully monitor your exposures.  If they are, in fact, overexposed, use the exposure compensation feature in the camera to tweak the exposure in 1/3 f/stop increments until you are happy with the results.  I took this portrait near Erfoud, Morocco, of a Berber woman in her tent.
