Picture of the day
An early example of
high-dynamic-range imaging
, captured by
Gustave Le Gray
in 1854. For this image, which was impossible at the time using standard methods owing to the extreme
luminosity
range, Le Gray combined one exposure for the sky and another longer one for the sea. Today, photographs with
high dynamic range
are primarily produced through
computer renderings
or merging multiple low-dynamic-range images; special image sensors, such as an
oversampled binary image sensor
, may also be used.
