Any comments on "normal" vs. reverse video? I use "reverse"
(dark on light) and constantly get ribbed by my coworkers who
mostly use light-on-dark (the status-quo "normal").
I got the same reaction at Xerox (only in reverse) as I use
white-on-black. My rationale (apart that after years of it I find it
hard to change) is that the less light my eyes have to deal with the
better. And nothing is worse than attempting to read an out-of-focus
or saturated black-on-white screen!
For clarity, what I do is:
o close the blinds
o use as dim a screen as is clearly visible, with as high contrast as
possible
o use incandescent lights. Fluorescents are usually too bright.
These changes easily give me two or three hours more with the console
before it becomes impossible to focus.
I sometimes feel I can read reverse better at a distance, and
that it is more "natural" (ala dark letters on light paper),
though I rarely can be convincing to a "non-believer"!
I can simpathise! But black-on-white, being actively bright, doesn't
remind me of a sheet of paper which is passive. Mais chacun a son gout!
