Today's featured picture

Early high-dynamic-range image

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.
