[sane-devel] scanner as digital camera back

[Jo Dierickx]

Hi,
I converted my canon lide30 to a digital back for my cambo wideframe
camera, as in this project.
You can find some pictures I took here.
I've used this scanner setup with vuescan on vista and xsane on
ubuntu. As you can see on the examples it has the capability to
reproduce grate gray scales.
But, i only get great result in shallow light conditions, and the most
odd black and white spots appear.
I don't know jack sh...t about scanners and since i believe its all
about the more advanced settings i turn myself to what i believe are
the experts, the back end developers like you all.
 About grayscales and lightconditions i think it would be a lot better
to have a scanner that can have its exposure time set. (preferably the
real exposure since analog gain is going to be difficult cause i
destroyed the led). Is this true, and does anyone know wich scanners
support this function?
About the light and dark spots, i'm very confused. This also apears in
the area that is not exposed to the light, it even apears when i keep
the camera closed. And yet is also dependant on the picture.
Can i start with this explanation and see where this query is taking me(us)?
Thanks
Jo
