I had always assumed that 8 bits per primary were enough to make the transitions between levels invisible, until I was shown a counter example similar to the author's. I verified with an image editor that the bands were indeed only 1 LSB apart. Given that 8 bits isn't perfect, even if there's no further processing involved, it's reasonable to set a higher goal.
- keeperofdakeys 13y agoAre you familiar with dithering? While it may seem like cheating, it really works quite well. It's similar to some LED torches, that use PWM to control brightness. They turn on and off really fast, and the more time they spend off, the dimmer the light. Yet you think it's a constant source of light, with a large enough frequency. For dithering, you just need a large resolution.
- mark-r 13y agoI'm very familiar with dithering, thanks. It was in that context that I was shown the example - I was wondering why anyone would feel the need to dither down to 24 bits.
