Selective measurement

from Wikipedia, the free encyclopedia

In photography, selective measurement is a type of exposure measurement in which only part of the image is captured (typically less than 10% of the image). If the range of the selective measurement is kept very small, one speaks of spot measurement .

The selective measurement can be used to:

  • determine the exposure based on a small part of the picture or
  • to capture the contrast of the subject by measuring several points (light and dark areas).
