When digitizing photographic negatives, there is always “more image information than meets the eye”. Subtle shades of grey often lurk within the shadows [and in the highlights] of photographic negatives. Conventional scanning systems have a limited range of tones that they can effectively capture and render. Sadly, this produces images that are often lacking in depth, complexity and vibrancy. The staff of the Digital Production Center has been using a special digitization technique and associated software to greatly expand and enhance the tonal range that is available for capture. The resulting images contain a tonal range from dark to light that more accurately expresses what the eye can see. This technique was extensively used during the production of a traveling exhibit of photographs by Hugh Morton, one of North Carolina’s most notable photographers.
