there is no especially relevant relationship to the range of 'stops' recordable by the camera or film and the range of brighness stops between pure white and max black on a print. there may be limits to the range of tonal steps on paper if 1/ the printer is 'noisy' in its delivery and cannot reliably produce specified shades of grey and 2/ the screening process is incapable of producing a consistent dot small enough to simulate comparable internmediate shades. In theory, infinite tonal steps can be produced in a range so small that to human judgment it is one flat color. the only advantage (digitally or in analogue) in having a greater range available pre output on a lesser device is flexibility to change the image dramatically and still end up with the maximum fidelity available via that contraption philip =============================================================== GO TO http://www.prodig.org for ~ GUIDELINES ~ un/SUBSCRIBING ~ ITEMS for SALE
