A fine grain master positive is a photographic term. It is also known as a fine grain master or fine grain and is a high-definition black-and-white intermediate positive image generated from a negative for the purpose of creating additional duplicate negatives. This intermediate element is exposed and chemically processed to a photographic gamma that will permit duplicate negatives as close to the original as is possible by a photochemical process.
While a fine grain master appears over-exposed and dark, it contains all of the information in the original negative, compressed into the toe and straight-line portion of the H&D curve via exposure and chemical processing. The image is uncompressed when the duplicate negative is made from the element and the tonal range expanded up into the top straight-line and shoulder portion of the H&D curve.
Famous quotes containing the words fine, grain, master and/or positive:
“Comes from a fine family. So she tells me. Brother’s a priest, all that. But, you know, death, disaster, unfortunate investments. One day she’s a little princess, up on the hill. Next, she’s down there, working the bars for the best she can.”
—Peter Prince, British screenwriter, and Stephen Frears. Harry (Bill Hunter)
“He never doubts his genius; it is only he and his God in all the world. He uses language sometimes as greatly as Shakespeare; and though there is not much straight grain in him, there is plenty of tough, crooked timber.”
—Henry David Thoreau (1817–1862)
“[Women’s] apparent endorsement of male supremacy is ... a pathetic striving for self- respect, self-justification, and self-pardon. After fifteen hundred years of subjection to men, Western woman finds it almost unbearable to face the fact that she has been hoodwinked and enslaved by her inferiors—that the master is lesser than the slave.”
—Elizabeth Gould Davis (b. 1910)
“The learner always begins by finding fault, but the scholar sees the positive merit in everything.”
—Georg Wilhelm Friedrich Hegel (1770–1831)
