Aperture Priority

Let’s talk a little bit about Aperture.

Photos taken with a low aperture let in more light, allowing you to take pictures in situations where there is not much light (like indoors and at night).

A low aperture will also give you a shallow depth of field. You know, the photos where one thing is in focus and the background is blurred....

A Brief History Of Television

A German inventor named Paul Nipkow invented the first rotating disk that would allow pictures to transmit over wire in 1884. His discovery was the first electromechanical television scanning system in the world. This rotating disk would rotate at a fast pace, while light passed through the holes to create a picture on a screen.

John Baird became famous when he invented the first pictures in motion that were televised in Europe in 1924. He later transmitted the human face onto a screen, and during World War II invented the first color picture tube. While it would be some time before color TV became a staple in American households, his contribution to the history of TV was enormous.

Charles Jenkins invented a mechanical television that he called “radiovision,” which was said to have transmitted one of the first moving images in 1923. This American inventor went on to promote his theories in the technology of the television along with other inventors when they transmitted the first live pictures onto a screen. This pilgrim in the history of the television is also famous for creating the first television station in North America.

Vladimir Zworykin invented the Cathode Ray tube, which he named the Kinescope and started a new era in the history of TV. Before the Kinescope, televisions in the 1920’s were mechanical. The Cathode Ray tube was not only needed for transmission; this device transformed the television into an electronic device.

Finally, an American farmer named Philo Farnsworth made a breakthrough in the history of TV at the age of 13, when he discovered a way to transmit images onto a screen by the use of 60 horizontal lines, which made the picture clearer. Farnsworth also invented over 165 devices, including the dissector tube, which became the groundwork for televisions we use today.

The Canon EOS-1D C* represents a breakthrough in cinematography in a DSLR specifically designed for video, that is incredibly flexible, rugged and compact. Offering onboard 4K image capture, industry-standard codecs and interfaces, and incredible low light performance, the EOS-1D C helps make 4K filmmaking as creative as you want it to be.

For anyone familiar with Canon’s EOS 5D Mark II or the EO
S-1D product line, the compact size and weight of the EOS-1D C will be immediately recognizable. Built with onboard 4K recording at 24P or HD recording at a range of frame rates up to 60p; and Clean HD via HDMI, the EOS-1D C offers additional capabilities for film and TV production as well as specialty image acquisition applications.

Coupled with Canon’s compact EF-mount lenses, the EOS-1D C facilitates 4K image origination in the tightest and most challenging environments, opening up fresh cinematic opportunities along the way.
