Most digicams with a bw mode achieve it by simply doing a 'forced dump'
of the color information...from rgb to gray scale. That's what Photoshop
does if you go to Image - Mode - and convert...it cuts the file size by
about 2/3 throwing out the color info...And the resulting image does not
look like "real" black and white....But it is possible to use the
channel mixer in Photoshop to make an RGB file look like bw..there are
some commercially available actions that do this extremely...

The new Olympus 5060, 5 mgp p&s, appears to take the later road to
producing b&w images in the camera. Set it to b&W and you can view and
shoot as though it was a camera with b&w film..(in effect). And when you
download you find that you have rgb b&w images that are the same file
size as the regular color images. And when I run those images through
one of the commercial actions, they don't change in appearance, which
suggests to me that the Oly engineers have, in effect, built such an
action into the camera.

What this means is that you can use this little delive to shoot "real"
b&w...and I then said I hope they are going to add something like this
feature to the E-1 DSLR....

I hope that explanation is clearer.....

I don't understand what you mean.
