Camera History & Parts

The camera obscura effect was discovered by greek an chinese philosophers and came to be know as the first camera, the obscura effect is achieved when inside a dark room a small hole in the wall projects light an through the hole the light is focused on the opposite wall upside down. In the 17th century Isaac Newton an Christian Huygens pieced together an perfected high quality glass lenses and optics, thus bringing man a step closer to modern cameras. In 1827 Joseph Nicephore added the last pice of the equation to successfully build the first portable camera, film. Still to this day Nicephores camera and modern cameras are very similar when it comes to the aiming, pointing, and shooting. Digital cameras capture pictures with an electronic sensor called a CCD unlike nicephores did. When taking a picture you have two modes Auto ( which is when the camera will completely control flash an exposer) and Program ( which is basic point and shoot and unlike auto you can control flash and a few other camera options). The portrait mode is when the camera will try to blur out the background. The sports mode is mostly used for sports or fast moving moments which freezes the moment, the camera will try to use to fastest shutter. The half press is a easy and essential step to help beginners  with a camera due to its faster camera response time, more control over focus, and encourages better composition. Disabled flash, which is when the flash is off and the camera uses natural light. The auto flash, which is usually on by default will flash if the camera thinks it needs more light. When your photo is exposed to too much light it will be washed out or too bright. If the photo doesn't receive enough light it will be too dark. The term " Stop" represents a change in the light. The new stop will be 1 stop brighter if the new planet has two sons instead of one. If there is 4 sons instead of 1 then the stop will be two times brighter. A longer shutter speed has more light vs. a shorter shutter speed which has less light. The aperture is like the pupil of your eye, you can increase the amount of light with the aperture by making the opening of the aperture larger.
