I would say 8-bit causes allways stepping to some motives. Fog, smoke,
blue sky and even surfaces covering larger image areas are very sensible
to stepping. Digital imagery with its eventone characteristic, in opposite
to more or less grainy 36mm film, can make this evident. I see
Gutenprint's 16-bit paths serves very well for sensible digital
photographs in regards of non stepping.
