Movie camera

The movie camera, film camera or cine-camera is a type of photographic camera which takes a rapid sequence of photographs on an image sensor or on a film. In contrast to a still camera, which captures a single snapshot at a time, the movie camera takes a series of images; each image constitutes a "frame". This is accomplished through an intermittent mechanism. The frames are later played back in a movie projector at a specific speed, called the frame rate (number of frames per second). While viewing at a particular frame rate, a person's eyes and brain merge the separate pictures together to create the illusion of motion.

Since 2010's, film-based movie cameras have been largely replaced by digital movie cameras.

History

Early experimentation

The very first patented film camera was designed in England by Frenchman Louis Le Prince in 1888. He built and patented an earlier 16 lens camera in 1887 at his workshop in Leeds. The first 8 lenses would be triggered in rapid succession by an electromagnetic shutter on the sensitive film; the film would then be moved forward allowing the other 8 lenses to operate on the film. After much trial and error, he was finally able to develop a single lens camera in 1888, which he used to shoot the first sequences of moving film in the world, including the Roundhay Garden Scene and Leeds Bridge. According to Adolphe Le Prince, who assisted his father at Leeds, Roundhay Garden was shot at 12 frame/s and Leeds Bridge at 20 frame/s. His camera still exists with the National Media Museum in Bradford. He shot the film on celluloid with 1¾ inch width.

Camera

A camera is an optical instrument for recording images, which may be stored locally, transmitted to another location, or both. The images may be individual still photographs or sequences of images constituting videos or movies. The word camera comes from camera obscura, which means "dark chamber" and is the Latin name of the original device for projecting an image of external reality onto a flat surface. The modern photographic camera evolved from the camera obscura. The functioning of the camera is very similar to the functioning of the human eye.

Functional description

A camera may work with the light of the visible spectrum or with other portions of the electromagnetic spectrum. A still camera is an optical device which creates a single image of an object or scene, and records it on an electronic sensor or photographic film. All cameras use the same basic design: light enters an enclosed box through a converging lens and an image is recorded on a light-sensitive medium. A shutter mechanism controls the length of time that light can enter the camera. Most photographic cameras have functions that allow a person to view the scene to be recorded, allow for a desired part of the scene to be in focus, and to control the exposure so that it is not too bright or too dim. A display, often a liquid crystal display (LCD), permits the user to view scene to be recorded and settings such as ISO speed, exposure, and shutter speed.

PBS Digital Studios

PBS Digital Studios is a YouTube channel and network through which PBS distributes original educational web video content. It comprises both original series and partnerships with existing YouTube channels. Most of the series are about science, pop culture, art, food, news, and music, though the channel originally launched with a series of video remixes based on PBS icons such as Mr. Rogers.

History

PBS Digital Studios founded by Jason Seiken in June 2012. They had their first viral hit with a "remix" of autotuned vocals from Mr. Rogers' Neighborhood titled "Garden of Your Mind."

The PBS Digital Studios network has received more than 500 million views and has over 7 million subscribers. Popular series found on their channels include Crash Course, Blank on Blank, It’s Okay To Be Smart, and the multiple Webby Award-winning PBS Idea Channel. Each month, the shows average more than 5 million streams.

Its first scripted series, Frankenstein, MD, launched on August 19, 2014 and ran until October 31, 2014.

Crash Course

Crash Course (also known as Driving Academy) is a 1988 made for television teen film directed by Oz Scott.

Plot

Crash Course centers on a group of high schoolers in a driver’s education class; many for the second or third time. The recently divorced teacher, super-passive Larry Pearl, is on thin ice with the football fanatic principal, Principal Paulson, who is being pressured by the district superintendent to raise driver’s education completion rates or lose his coveted football program. With this in mind, Principal Paulson and his assistant, with a secret desire for his job, Abner Frasier, hire an outside driver’s education instructor with a very tough reputation, Edna Savage, aka E.W. Savage, who quickly takes control of the class.

The plot focuses mostly on the students and their interactions with their teachers and each other. In the beginning, Rico is the loner with just a few friends, Chadley is the bookish nerd with few friends who longs to be cool and also longs to be a part of Vanessa’s life who is the young, friendly and attractive girl who had to fake her mother’s signature on her driver’s education permission slip. Kichi is the hip-hop Asian kid who often raps what he has to say and constantly flirts with Maria, the rich foreign girl who thinks that the right-of-way on the roadways always goes to (insert awesomely fake foreign Latino accent) “my father’s limo”. Finally you have stereotypical football meathead J.J., who needs to pass his English exam to keep his eligibility and constantly asks out and gets rejected by Alice, the tomboy whose father owns “Santini & Son” Concrete Company. Alice is portrayed as being the “son” her father wanted.
