Q) I know you've answered this in the past, I but can't seem to find my issue. I want to get a polarizer for my camera. Which type should I get?
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) What's the best way to control noise when shooting? I recently took some photos of the Northern Lights and the results were very noisy.
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 worthwhile exploring.
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?
