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.

“I love you. I never told my parents that I loved them. ‘Course, they never told me that they loved me, either, which was fine with me. But I love you.”

“Your master Robin Hood lies dead,
Therefore sigh as you sing.
Here lie his primer and his beads,
His bent bow and his arrows keen,
His good sword and his holy cross:”
—Anthony Munday (1553–1633)
“Blessed be the inventor of photography! I set him above even the inventor of chloroform! It has given more positive pleasure to poor suffering humanity than anything else that has “cast up” in my time or is like to—this art by which even the “poor” can possess themselves of tolerable likenesses of their absent dear ones. And mustn’t it be acting favourably on the morality of the country?”
—Jane Welsh Carlyle (1801–1866)
