Camera History

Camera History

• The camera obscuration affect is an effect achieved by making a hole in a wall of a dark room, and the outside scene is projected on the dark wall, this was the first ever camera.
• In the 17th century the modern camera was a step closer Thanks to Isaac Newton and Christian Huygens, the invention was the glass lense.
• The first parts of the first modern camera was the film,and was inverted by Joseph Nicéphore Néipce.
• Something that modern digital cameras and Néipce's camera have in comon is that they both have glass lenses.
• digital cameras and the very first cameras still work in the same way except that digital cameras capture the photograph on a digital film instead of the older film strips used before. 

Camera Modes

• auto mode and program mode are different because in auto mode the camera will control the flash and the exposure for you. so it will basically do the things for you, and in program mode the camera has automatic-assist so it is easier to just "point and shoot" and you can control some things like the flash and some other settings.

• portrait mode is normally used for taking portraits of people or things, and what it does is blur the background so that the thing being captured is more in focus and looks like the center of attention.
• sports mode is used when things are moving fast and freezes motion so the image comes out clearer, it does so by using the fastest shutter possible.

Half Press

• the half press is used to focus in on one thing and make sure the picture is going to come out clear.

Controlling Flash

• the symbol means that flash is turned off, you usually use this when there is enough light for the picture to come out clear.
• the symbol means that flash is set to automatic so it senses how much light there is and automatically turns on or off.

Intro to Exposure

• if there is too much light the picture will be washed out.
• if there is not enough light the picture will be dark.

The Universal Stop

• a stop is a relative measurement of light
• if there are two suns instead of one the planet would be +1 stops brighter.
• if there are four suns the planet would be +2 stops brighter.

Shutter and Aperture

• a longer shutter speed means that more light will be captured.
• a shorter shutter speed means that there will be less light captured.
• aperture controls light.
• when adjusting apreture you can increase the amount of light by opening up the shutter.
