I was doing 150dpi greyscale jpegs. I've changed to 400dpi 1bpp tiffs,
and now I'm ending up with each page about 700K... (scan as greyscale
tiff (unknown compression), convert to 1-bit with lzw compression, save
as pdf in Photoshop).

Using tiffcp to change the compression from lzw to g4 more than doubles
the size to 1.6 MB. That's for a single page.

Surely this is too large?
