What Dan said, plus—
Often I find an rgb file from my camera to be different from my rgb files
from my scanner when converting to black and white. They are kinda different
beasts. I often pick either the green channel or red channel from the channel
mixer for scanned color film, while with the digital camera, I use a mix of
the green and red channels.
In both cases I am starting with a 16 bit file, so there is plenty of room
for messing around with the file and maintaining data integrety. In fact,
almost all my black and white files now are kept in 16 bit up to and
including printing. This includes both digital camera images and scanned
images—color or black and white film.
It is also interesting how digital camera files can be manipulated in the
channel mixer for all sorts of effects, including infrared.

This depends upon your camera and what it rendered. I am speaking of
digital cameras. There is an 'action' in Photoshop which converts color
images (scanned or digital) to grayscale. It averages portions of each
channel and seems to be mighty smart in doing so. Try it. You will like it.
