Q) An interesting problem came up
recently with regards to evidence of bylaw contraventions in Pretoria,
City of Tshwane, South Africa. The City Councils officials have
switched to digital cameras for much of their work. However, it turns
out that in court proceedings, the magistrates/judges aren't prepared
to accept digital photographs as evidence because of the possibility of
"fabricating" evidence. This is a valid point, and they want
photographic film evidence, either positives or negatives. The question
then is whether there's any photographic processing done in-camera,
which leaves a watermark (maybe we should call that a "digimark"),
which will indicate when pixels in the original have been removed or
added, as opposed to colour, gamma and highlight or shadow adjustment
to improve the original photo WITHOUT altering any evidence that might

Balancing White Balance
Q) I'm starting to pay more

well. But there have been some situations where I haven't been
satisfied. So I'm wondering about custom white balance and whether I
should always be using that?

Q) I'm new to digital SLRs and want to photograph my son's indoor basketball games. Working in shutter- and aperture-priority modes, I can get sharp photos or bright photos inside, but haven't been able to get sharp, properly exposed photos without a lot of noise. My white balance and ISO are both set on auto. What am I doing wrong?

I'm given several different options for interpolation. People tell me

from film to digital, I'm fighting one problem that nobody told me

Playing Your Cards Right
Q) I've followed your recommendation about using a card reader instead of connecting my camera directly to my computer. But I'm not sure of formatting. It seems to be working fine. but I'm not sure I'm choosing the right option.
