My friend Richard Kadrey introduced me to infra-red photography. Sensors on digital cameras can detect infra-red, but normally are shielded from it by a protective filter that resides as a thin layer over the chip. You can hack a camera by removing the layer, but it is easier to buy a Fuji IS-1, which is infra-red-ready. If you use a lens filter that blocks the visible frequencies, the camera displays an image that consists of infra-red transposed into the visible spectrum.
Vegetation reflects almost all light below red, and thus appears “white.” Conversely, the upper atmosphere does not refract infra-red, and thus a blue sky appears “black.” An unexpected effect is that most fabric dyes reflect infra-red, so that a crowded sidewalk appears to be populated entirely by angelic people dressed in white.
During 2007 I drove across the country and took a bunch of infra-red photographs. The Southern states looked especially good, because they contain so much vegetation.

When the Congressional Science committee wants to talk about the cold weather, and when NASA has to defend their budget by explaining why NASA is important, it can make people who believe in facts… a bit tense.
If you want to work in tech, but don’t have any desire to code web apps to help businesses sell things to other business, you might want to consider a career in cybersecurity. Judging from the apparent complete infiltration of Russian hackers in American cyberspace, it seems fair to speculate that there’s a major shortage of […]
All moms are different. But all moms like getting flowers on Mother’s Day, and that’s a fact (not, however a fact we can document in any fashion.) Instead of getting chewed out for forgetting to call her on the second Sunday of May, you can take care of it ahead of time with Teleflora’s flower […]
Yeah, Bluetooth audio is pretty common these days, so why should you care about these earbuds? Look how happy that woman up above looks. She’s got FRESHeBUDS in. Boom. There’s your reason. She’s also at the beach and it appears to be a very nice day.But for the sake of promotion, wireless earbuds are fast becoming the […]
