Welll, it is an hard task and very annoying, since it depends from book size and I don't have a long tripod, but only a small 37 cm long tripod (maybe I need at least a 1,20 meters tripod) and I'm constrained to take camera in my hands do you know what camera model seems to have a decent focus aroun...

Re: Image magick (or other) program - grey bgnd to white ?

you should not save in jpg format if you want edit or post-process photos

I used jbig2enc

Code: Select all

jbig2 -s -p -v -T 115 *.jpg && pdf.py output>out.pdf
and this is the result (not optimal due to poor light and lossy format of jpg image)
