Optimize RAW files twice—once for highlights and once for shadows—for a better tonal range
One of the big challenges of photography has always been how to best capture the tonalities and brightness of the real world. Every film, every sensor (and its processor) will interpret it slightly differently.

Q) Since I've been using my digital SLR, I'm getting more and more worried about dust. I've noticed some of the newer cameras have some sort of dust-removal feature. I'm not able to get one of the newer cameras right now. What's the best way to avoid getting dust in the camera?

Lens Cap Madness
Q) I know this isn't a highly technical question, but the situation drives me crazy. When I take the lens cap off my camera, I never can remember where I put it. Any suggestions you could make would be sooooo helpful.

When To Sharpen

Q) I'm going on the trip of a lifetime in a few months and I was looking to stock up on memory cards so I don't have to bring my laptop with me. With prices coming down and card sizes going up, I thought I'd have an easy decision. When I got to the store, I became confused. There used to be just one flavor of SD; now there's SDHC. Should I try out the new cards?

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
be required in court. If not available yet, this is certainly

Balancing White Balance
Q) I'm starting to pay more
attention to white balance in my photography. I've read some of what
you and others in PCPhoto have said about not forgetting white balance
when shooting RAW. So now I've been trying some photography while
keeping the dial off of AWB. For the most part, it has been working
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?
