All images are monochrome. Color images are constructed by
taking multiple images through a variety of filters that can
be selected for specific wavelengths of interest. Most color
images may not be 'true' color, as imaging isn't entirely
about pretty pictures but chemistry instead.

Right, I just heard overnight that they get color pictures by taking
sussessive exposures using filters of different colors. But if there is
noticeable motion at the time of the exposures, then you can't get a clear
picture with that approach, so they just go with a monochrome image. (BTW
that single "color" could be white, or infrared, or UV or a number of other
possibilities.

--Damon, really looking forward to the Titan flyby images

Me too, but unfortunately, while Titan is probably going to be the most
colorful object on the whole tour, don't expect color pictures on this early
flyby--for exactly the reasons just described. A flyby is going to have too
much motion to get three successive exposures that match up.

This would depend on the exposure time - if it was short enough, then no
reason why not

I was wondering if Huygens is actually going to land on Titan, or is simply
going to crash into it, a la the Ranger series?

And speaking of which, all of Cassini's images seem to be in monochrome.
Doesn't it have a color camera as well?

from what I heard on NASA tv today, it will land on Titan.
