by mattmacf (#28099539) Attached to: Polaroid Lovers Try To Revive Its Instant Film

I don't think anybody really understands the reason Polaroid is still a popular medium. I'll give you a hint, it's got nothing to do with any of the bloody technical aspects of the film. It's not about megapixels or instant gratification. More than anything, Polaroids have a quirkiness and charm to them that isn't reproduced by anything else.

I'm a hobbyist photographer and even though most of my gear is digital, there's something to be said for some of the old school methods. Every once in a while I'll go out on a nice day and run a roll or two of slide film through my camera. Generally I'll take just one prime lens out for the afternoon and I won't finish until I'm out of film. Send the film out for development, wait several days, and get back about 98% crap. There's no cloning, airbrushing, leveling or curving. The exposure has to be spot on or it'll turn our too dark to see through or virtually transparent. Why do I do this? The one or two keepers you do get are something special. The tonal range, the color saturation: there's nothing digital that can compete.

Polaroids are even neater. Sure you can get functionally the same thing with any consumer point and shoot digital camera (take picture, check LCD, print later), but in comparison, the images you get can only be described as bland and mechanical. Not to mention watching your picture develop almost magically as you shake it. It's a great date idea too if you can find the equipment. Unfortunately, the film is now prohibitively expensive for shooting casually.

There are still enthusiasts who scour ebay only for long-expired Polaroids because of the unique color shifts that they give. There's also unexpired film still selling on ebay for well over $1/exposure. That's for a 3" square image that's got virtually no redeeming technical qualities to it. Again, there's NOTHING digital that compares.

It may sound hokey, but TFA puts it pretty bluntly:

âoeIt used to be something you use for a lighting test,â Ms. Bukowska said. âoeNow it is the art itself.â

Motor Made From Liquid Film 241

Posted by CmdrTaco from the makes-my-water-spin dept.
KentuckyFC writes "Last year, a group of Iranian physicists made a puzzling discovery. They placed a thin film of water in a small cell and bathed it in two perpendicular electric fields. To their surprise this caused the water to rotate. They called their device a liquid film motor and posted on the web a cool set of movies showing the phenomenon. The puzzle is this: the electric fields are static, so what's driving the motor? Now another group of physicists has the answer: a complex interaction between the electric field, the cell container and the liquid causes water to move along the cell wall. Crucially, it moves in opposite directions on opposite sides of the cell and so sets up a circular flow. The phenomenon works only when friction and surface tension are significant forces so the effect is entirely scale dependent. That's probably why we haven't seen it before and also why it could have important implications for microfluidic devices such as lab-on-a-chip."

Hippies Say WiFi Network Is Harming Their Chakras 432

Posted by samzenpus from the what's-with-all-the-negative-waves dept.
Anti-Globalism writes "A group of hippies is complaining that a recently installed WiFi mesh network in the UK village of Glastonbury is causing health problems. To combat the signals from the Wi-Fi hotspots, the hippies have placed orgone generators around the antennae." Although there have been many studies that show no correlation between WiFi and health issues the hippies say, "Yeah, well, you know, that's just, like, your opinion, man."
