It would sound reasonable to most of us ...
but I don't believe most of us
are aware of the RGB gamuts your microscopes
are capable of. Keep in mind,
even a wide gamut space like Ektaspace has
coordinate values tied to reality
( ... e.g., what Ektachrome is likely to see
through a Nikkor ..). I don't
know how many times I put an RGB image
together based on scientific sensors,
to be extremely disappointed when I moved it
into real world color spaces
(... "real world" ... get it? ... bruce? ...)
In any case ... I'm sure you are already
aware of the above ... it's just
that I don't believe most on this list are
aware of the RGB values you are
working with.
While raw R, G, & B signals coming off of a photomultiplier amplifier
as a video signal and A/D converted in my choice of 24, 48, or 96 bits
per pixel can give a huge gamut, I usually try to best-fit my signals
into an 24 bit per pixel signal for reasons of reasonable file size.
Further, the colors I am usually trying to achieve are those that fit
into the "natural" world color realm -- nothing outlandish or exotic
(well...maybe a bit exotic). The really neat thing is that when doing
digital ink jet printing, there is no MTF loss in the entire workflow.
The image NEVER goes through an optical path! Its electron illumination
converted to and electronic signal, then to digital. The prints that
have resulted are so sharp and detailed that I'm even amazed. Of course
its a bit different when I go out to film recorder. Didn't mean to
ramble on...I'll stop boring y'all.
