JPEG and Monochrome
I know there are quality issues if you try to convert any image to jpeg that has less than 16 grey levels. But is it possible to make a monochrome jpeg?.

It looks pretty crappy but seems to work...
convert -monochrome calvin.jpg mudd.jpg More options with: convert --help |
The result i get is 8bits per pixel which is greyscale.......are u sure your output was 1bpp monochrome?

Yep, I guess it's grayscale.
