Exposed with highlight preference
Creatively speaking however, another photographer may have been in this same
scene and been more interested in the baby in the shadows. A better exposure
for the baby would have been to expose for the shadow detail and let the
highlights blow out.
Summary of Histograms and Exposure Evaluation
Although it is important to learn to read histograms, it is also important not to
get too overly obsessive about them. The truth is that a good histogram does
not always equate to a good image and a bad histogram does not always dictate
failure. Sometimes loss of detail works, sometimes it does not. Knowing in the
i eld when you have exposed well for the important information as creatively
interpreted for a given scene, and when you need to reshoot, is the most valuable
advantage digital capture has to of er the photographer.
When shooting raw, it is important to know that there is a dif erence between
the clipping point indicated by the camera histogram and the clipping point of
the corresponding raw data. This disparity occurs because the camera histogram
is created from the in-camera JPEG conversion of the original raw data. In-camera
JPEG conversions typically discard 1-2 stops of the sensor's dynamic range,
(another reason to shoot raw), which means that there is usually about a stop of
extra leeway in the highlights information to play with in raw capture data. The
