I would disagree one point from B MacLiam below. Taking readable images of
documents in ambient light is in my experience quite difficult, unless very
brightly lit. Perhaps he has a better camera, but with my fairly basic model
(cost 165 euro in Dublin in 2006) photos in indoor artificial light are v.
difficult.
The problem is that to get enough light to the CCD sensor the camera needs
to use a long exposure, e.g. 1/10th second or longer, this means that camera
shake will be a problem and you get blurred images. To get a sharp image with
my camera you need to use a tripod or some sort of clamp.
If checking out a new camera, look for a large lens aperture
Good point. One big advantage digital cameras have over SLR is the
view-screen ... you can see before you snap if your exposure is sufficient. I have a
small table-top tripod which I routinely use, so I didn't even think about the
shake; but of course, you are correct about the aperture.
