ISO speed - photography techniques Film speed is the measure of a photographic film's sensitivity to light, determined by sensitometry and measured on various numerical scales, the most recent being the ISO system. A closely related ISO system is used to measure the sensitivity of digital imaging systems. Film speed measurement systems Historical systems Warnerke The Warnerke Standard Sensitometer consisted of a frame holding an opaque screen with an array of typically 25 numbered, gradually pigmented squares brought into contact with the photographic plate during a timed test exposure under a phosphorescent tablet excited before by the light of a burning Magnesium ribbon. The speed of the emulsion was then expressed in 'degrees' Warnerke (sometimes seen as Warn. or °W.) corresponding with the last number visible on the exposed plate after development and fixation.
The Other Mystery of Easter Island Moai statues Easter Island is branded into popular consciousness as the home of the mysterious and towering moai statues, but these are not the only curiosity the South Pacific island holds. Where the moai are fascinating for their unknown purpose and mysterious craftsmen, the island's lost language of Rongorongo is equally perplexing. The unique written language seems to have appeared suddenly in the 1700s, but within just two centuries it was exiled to obscurity. Known as Rapa Nui to the island's inhabitants, Rongorongo is a writing system comprised of pictographs.

Photographers rights: When, where and what can I shoot? Is the title clear enough for you? If you don’t ever want to end up like Rocky with your face all swollen because some security personnel decided you were a national threat, or you want to be completely sure that you can take that shot of your favorite celebrity pissing in the garden, this guide is meant to give you some clarity over what you can and can’t do with your camera.

BOOK of KAOS Tarot Originally titled, 'The Bohemian Tarot' -(underwhich the original Major and Minor Arcana sets were published seperately as A5 limited-edition (100 copies) folios around 1991) I redrew about half of the major arcana a decade later to form the deck into 'The BOOK of KAOS', an inter-sect-ion of ChaOrder Magick and the aeonic double current of Horus and Maat.

A Father Who Creatively Captures His Kids (20 photos) If there was a prize that could be given out to the most creative father, I'd hope that it was awarded to Jason Lee. A wedding photographer by day, he's used to capturing some of the most important moments in a couple's lives. As a longtime fan of Jason's photos on Flickr however, I think the real magic happens when he turns the camera onto his daughters. Sure, his children are adorably cute in their own right, but that's not what makes his photos so interesting. It's when he puts his own spin on their everyday moments that we not only get to experience our own childhood again, we're able to see a father's pride shine through.
