If we printed that image 4256 / 240 = 17.7 inch print we'd not see that very faint but sharp grain at at all.! I see it being a grainless 11x17 inch print. But at 1:1 as we see it blown up on our monitors we now with the software see instead of faint sharp grain we see less faint week old mushroom grain. Which again would proably disappear once it was printed or rezzed down to look good a a typical web layout. . Mark William Rabiner
