large schematics - was RE: [sebhc] H-89 bus pin out Help

It won't work.  An 8.5" x 11" page at 300 dpi is 9 megapixels (but even with
a 9MP camera, you won't even come close to scanner quality due to focus and
lens issues).  Here, we are talking about pages which are 8 times that size.
You have a 72 megapixel camera?  (not to mention the lens and focus issues)

Hi
 Has anyone tried photographing with a good camera.
I have a access to a Canon D10 that can create a
TIF file. There must be some way to convert this to
a pdf.
