Digital Camera On Sale Details
Practical imaging systems, digital and film, have a limited "dynamic range": the range of luminosity that can be reproduced accurately. Highlights of the subject that are too bright are rendered as white, with no detail; shadows
that are too dark are rendered as black. The loss of detail is not
abrupt with film, or in dark shadows with digital sensors: some detail
is retained as brightness moves out of the dynamic range. "Highlight
burn-out" of digital sensors, however, can be abrupt, and highlight
detail may be lost. And as the sensor elements for different colors
saturate in turn, there can be gross hue or saturation shift in
burnt-out highlights.Some digital cameras can show these blown highlights in the image review, allowing the photographer to re-shoot the picture with a modified exposure. Others compensate for the total contrast of a scene by selectively exposing darker pixels longer. A third technique is used by Fujifilm in its FinePix S3 Pro digital SLR. The image sensor contains additional photodiodes of lower sensitivity than the main ones; these retain detail in parts of the image too bright for the main sensor.
