"I’ve been doing some experiments using Processing to generate different patterns and sequences, a projector, and a camera pointing to the projection screen. Some of them are using a technique called procedural light painting, some other combining slit-scan with projected patterns. I’m also very interested in the low repeatability of some of these experiments, like the picture above, due to the noise introduced by the asynchrony of generation, communication and output means. Maybe we can call it Generative Photography." Really nice; interesting overlaps with some of the stuff from Shadow Catchers (in terms of structuring the capture, rather than the release, of light).

"Truth be told, I don't think in terms of absolute F/stops and shutter speeds. They are not what is important. It's the relationship between the different light levels that is important." Ding! I like Hobby because, so much of the time, he uses the language I use. Exposure is relative: talk about it like it is.

"When he has mastered tone, and with it exposure and development, he knows the most difficult part of his technique and practice, let him then proceed to picture-making." Emerson's Naturalistic Photography for Students of the Art, 1889.

"Privacy is not simply about the state of an inanimate object or set of bytes; it is about the sense of vulnerability that an individual experiences. When people feel exposed or invaded, there's a privacy issue." Loads in here that's of use beyond this qu

Not so much "tedious" as thorough. Really well written, really clear. If you're a photographer and you *still* don't get this stuff, you need to know it now. And then you need to know it backwards, because it's basically the entire technical side of thing

Complex, comprehensive, worth going back to; interesting for those times when you don't want to use the light meter.
