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.

“Alcohol doesn’t console, it doesn’t fill up anyone’s psychological gaps, all it replaces is the lack of God. It doesn’t comfort man. On the contrary, it encourages him in his folly, it transports him to the supreme regions where he is master of his own destiny.”
—Marguerite Duras (b. 1914)
“A positive learning climate in a school for young children is a composite of many things. It is an attitude that respects children. It is a place where children receive guidance and encouragement from the responsible adults around them. It is an environment where children can experiment and try out new ideas without fear of failure. It is an atmosphere that builds children’s self-confidence so they dare to take risks. It is an environment that nurtures a love of learning.”
—Carol B. Hillman (20th century)
