Cameras

Low Iight Camera which can work in weak light condition is a kind of Hidden and (or) Security Camera, involving Moon type, Star type and IR type.

Such high sensitivity cameras as Moon grade and Star grade can normally work in tiny light condition and 1~3 Lux is the general illumination (the "Illumination" is measured by "foot candles." According to Engineering Tool Box: "A foot candle is actually one lumen of light density per square foot, one lux is one lumen per square meter." Engineering Tool Box also states that the recommended indoor illumination level is 500 to 1,000 lux).

Moon type: normal work needs around 0.1 lux illumination.

Star type: normal work needs below 0.01 lux illumination.

IR type: IR light source, even can image Black/White picture in 0 lux condition.

The pinhole camera noted by Aristotle in the 4th century BC. later became known as the Camera Obscura, a term introduced by the Italians meaning "a dark room". The first pinhole did not use film, but the camera was so big eg, a room or box size, that the taker was acutally inside the camera and was simply tracing the images by hand. Kinda like paint by colors. And who knows, maybe the pinhole effect could have been observed from early man who saw images in caves produced by a small light opening in the cave??? Anyhoo, the Italians used the Camera Obscura during the 16th Century and was an aid by artist of the Renaissance eg, Guardi, Canaletto. Leanardo Da Vinci noted the possibility's of the camera. The "lens" did not actually come about until aprox. 1530 AD possibly by Daniel Barbaro.

Ansel Adams invented the Zone System.

The Zone System allows the photographer to precisely expose the most important element in his photograph. You use a spot meter and measure every important thing in your image, bearing in mind white, black and gray objects all reflect different amounts of light but the meter thinks they're all gray--because that's what a meter is designed to do. After doing all the math, you dial in an aperture and shutter speed that will allow you to capture the scene as close to how it appears as you possibly can.

This worked for Ansel Adams, and it will work for anyone who's really familiar with relative reflectance and isn't shooting something that moves or changes. You can't shoot a basketball game with the Zone System, for instance, and you can't shoot sunsets because you don't have time to meter them.

It is a special tool including a camera attached to an animal for pictures and info. Was invented by a marine biologist . Hopes this helps. For more details go to national geographic.

Camera obscura.Photographic cameras were a development of the camera obscura, a device dating back to the ancient Chinese[1] and ancient Greeks,[2][3] which uses a pinhole or lens to project an image of the scene outside upside-down onto a viewing surface. On 24 January 1544 mathematician and instrument maker Reiners Gemma Frisius of Leuven University used one to watch a solar eclipse, publishing a diagram of his method in De Radio Astronimica et Geometrico in the following year.[4] In 1558 Giovanni Batista della Porta was the first to recommend the method as an aid to drawing.[5]
