Dave McDonell on Noise

Dave McDonell, cofounder of Imagenomic, the company that makes Noiseware, my favorite noise reduction software weighs in on noise.
JPC    Where does noise come from?
DM    There are several factors in a digital camera capture process that contribute to noise. The most prevelant are temperature, the actual capture circuitry, sensor size, and the process of sub-sampling which induces errors between adjacent pixels.
JPC    Why is chrominance noise so much easier to reduce than luminance noise?
DM    It’s really not in application. It’s just that you perceive changes in luminosity or brightness much easier than you do in color.
JPC    Fine color noise is easier to reduce than coarse color noise, like the color patterns created by demosaicing bayer patterns. When are you most likely to encounter this type of noise? How should you treat it differently? How far can you go?
DM    There are no hard and fast rules for any of the above questions as all are dependent on the capture situation and subsequent output medium.

Sat., Sept. 26, 2009, 8 pm, Planet Green Network airs A Sea Change.
A Sea Change documents an extremely pressing issue, acidification of the world’s oceans. It’s an often overlooked aspect of climate change. Essentially, it’s getting harder and harder for marine life to form shells because the oceans are rapidly becoming more acidic. The point of no return is projected by scientists to be less than 50 years away.
Look for Planet Green content on cable, Direct TV, and more. It’s the  first & only 24-hour eco-lifestyle TV network. A Sea Change airs as part of Planet Green’s “Reel Impact” series. They’re in terrific company: also airing are An Inconvenient Truth, Who Killed the Electric Car, and No-Impact Man.
Tell your friends. Email your representatives. The oceans aren’t on the table at the upcoming summit COP-15. That needs to change.
