extract high resolution b/w from color?

Is there a way to extract a black and white image from a color digital slr
with higher resolution than the color version?

I think so - I believe that some RAW software can do this,
assuming the colour data is from a Bayer matrix.

The basic answer is no.
However this begs the question, why do you need higher resolution of
you original image?

Certainly making a good B&W conversion in CS using color filters in an
adjustment layer, or using channels rather than gray scale or
desaturation, can give the illusion of enhanced contrast and detail.

If your intention is to produce a massive print then look to Genuine Fractals

No but some have tried chemically removing the bayer filter for b&w with
better low light performance and I think that takes the microlenses off
too, and if you took off the antialiasing filter, it would look a lot
sharper but have jaggies & moire pattern problems.

If you have a recent version of Photoshop, it can be used to both make a
fine conversion to B+W and up rez to make larger prints than the pixels
might suggest.

Go learn what "begs the question" really means.

usage (stupid media personalities notwithstanding).

That the language is disintegrating. We can either sit back and observe, or
complain about it.

They are our two alternates.
The language is being totally decimated.
I have no time for disinterested armature linguists who don't give a
tinker's cuss for accuracy, and except such errors, loosing site of the
original meaning.

Be careful of the position you take, your armature is showing.
