Read this interesting article by Dirck Halstead,
a Whitehouse journalist who actually uses the Pro70 in the Whitehouse
for press photos (interesting)...
Part of the
answer to this problem may have arrived with the introduction
of the Canon Pro70 digital camera. For less than $1,900 it
is possible to buy a camera, with all the necessary peripherals
for hook up to a laptop, that is capable of delivering a magazine-usable
image. It is not going to have the same quality as if it were
shot on film, however, it will not appear noticeably different
from the photos the wire services will provide.
