Noise Reduction
The A700 initially received criticism from the review community for their "cooked raws", a function that kept the noise reduction algorithm on in the image on high ISO even on Raw files, hence, "cooked" into the raw data. Shortly after the release, Sony released a series of successive firmware updates, finally ending on version 4 which improved function, including allowing a variable setting for noise reduction including the option to turn it off; the cooked raw problem was no longer an issue. Some other improvements were exposure bracketing extended 2 EV, and high ISO image grain improved.

Famous quotes containing the words noise and/or reduction:
“The square dance fiddler’s first concern is to carry a tune, but he must carry it loud enough to be heard over the noise of stamping feet, the cries of the “caller,” and the shouts of the dancers. When he fiddles, he “fiddles all over”; feet, hands, knees, head, and eyes are all busy.”
—State of Oklahoma, U.S. public relief program (1935-1943)
“The reduction of nuclear arsenals and the removal of the threat of worldwide nuclear destruction is a measure, in my judgment, of the power and strength of a great nation.”
—Jimmy Carter (James Earl Carter, Jr.)
