hi Jo
I've debayered a 350d as well (scraped off the microlens layer and the cfa layer underneath) and you do not need to debayer.
to get b&w, take a pic of a white screen on your laptop, use that as a custom white balance and then take images as raw+jpg. you'll see that the jpg's are in black and white with no colour.
I normally open the raw in maxim and save as fits and then stack in dss as you can set the fits in dss to be treated as mono.
the other option is to use a program called dcraw and save as tiff.
finally you could use the jpg's themselves if youre testing.

as you'd know, the af on lenses wont work if you dont have the cover glass so you'll have to focus manually or add an ir filter glass.

and yes, the microlenses do get removed as they are above the cfa layer.


cheers
Alistair
