Here's what I have so far, and as far as capturing the text close to the gutter it works perfect.
The pressure from the bottom edge of the glass serves to press the opposing page out of the
line of sight. (Second picture)
The kit lens that comes with the XS actually let's you get 2.5" closer then the manual says. I'm about 8"
from the glass with some extra zoom to spare. This allows me to get almost all the 10MP on the page.
The camera is on the pivot point so it takes virtually no time for any vibration to settle down. What I'll
do before I start taking a bunch of pictures is to take the first one with the auto focus, and then use some
blue painters tape to keep the focus in place then switch off the auto focus not to wear it out. I'll just put it
in manual mode and use the same shutter speed, aperture, and ISO as the first picture. I have an AC adapter
so the batteries are not a concern.
To move it up and down I can either grab it from the part extending out beyond the camera, or
right in front close to the glass. I will have to use it a little while to determine the best place for me.
Then I will mount the remote shutter switch there.
I still have a few details to work out, such as something to mount a light to which is very simple.
Another is a good way to hold the book, but I have a few ideas on that also.
You can also adjust the distance to the camera as well as moving the glass up and down to keep
all sizes of images centered to capture as much of the page as you can with the most MP's.
Any comments or suggestions?
