New deepest black

[Andrew Farkas]

So this black is the darkest black yet, but can your eye tell the difference? Does that make photographers want it any less?

Hi CG,

you are right .. I remember very well an experiment in which that shoe cardboard box with a hole to look at and some black velvet to compare with was shown .. the absolutely black velvet had a look of light-grey compared to that max obtainable black of that box .. there is no blacker black than that ... so if you take a repro lens and mount it on a long tube .. paint the interior black with some matte black .. and when looking through it .. it will appear light grey .. only when you introduce several round and thin baffles to eliminate practically all internal refelection you will have superb contrast on film .. and that can be obtained by any of us amateur designers if for example you mount a 600mm lens on a SL66 .. etc. Internal flare through reduction of contrast kills resolution of fine details .. but it can be controlled very easily by above simple means.

Best

Joerg

New OLED technology is appearing in the display arena. Sony produced a 11" and 27" OLED TV's that feature 1,000,000 contrast ratio and and >100% NTSC color reproduction. This is because the OLED element can be turned off producing a black that has yet to be experienced in CRT or LCD technologies. In 5 years or less full size OLED monitors will be available. Sony is already working on these products.
