Re: A82: Grayscale?




In my experience the best way to use greyscale as it currently exists is
sparingly, and usually around lots of non-grey areas. For example, a block
of grey will look terrible due to the flicker/diagonal-effect but if the
block is mostly white or balck, the effect is far less noticeable.
Probably the best use for it, in terms of visual quality, is as a means to
anti-alias hard black edges. Since you have to store twice as much data
and write twice as many times to memory (in general) to achieve the
effect, it in most cases is not worth doing.
