Photography may also be referred to as the process of creating moving or still pictures by means of capturing live data by way of observing radiations and store it on sensitive medium similar to electronic sensors or electromagnetic film.
The camera is an image forming device while the photographic film or electronic image sensors serves as its recording medium. In this modern time, digital cameras have electronic medium which serves as its storing medium. The idea behind camera is, it controls the amount of light and the time exposure of the camera to the outer world by using a lens. So long as there’s enough amount of light, it is possible to generate an image on film. The raw image can be developed to get real time original image. Movie camera is yet another kind of camera which is basically the total movements are captured and not just the stills. The idea behind a movie camera is that it captures data in series of photos without delays in between them. This as a result creates a moving frame that is typically captured with the voice.
We need to be certain that we’re adjusting the camera either automatically or manually to be sure that we’re going to get a clear and sharp photograph. Following are some camera controls along with its descriptions.
Number 1. Focus – this adjustment is extremely important if you wish to bring the desired part or desired area to the sharpest point possible. Normally, this can be done manually but can be done automatically too especially in latest models of digital cameras.
Number 2. Aperture – this may be referred to as adjustments of iris or otherwise known as the “f” number. Usually, this number is controlling the amount of light that is going to pass through the camera’s lens. The aperture is known to create some effect on the depth of field and focus.
Number 3. Shutter speed – this is controlling the speed of shutter with which it opens and closes are referred as shutter speed. Most of the time, this is done in milliseconds, which is the same time that the imaging medium and light are exposed to storing medium.
Number 4. White balance – this is a special feature in many digital cameras used to ensure that white light is captured as it is in real medium so colors in imaging area look natural.
Number 5.Metering – this measures the amount of exposure of light and done manually in order to make sure that bright light areas as well as shadow regions are captured based on the photographer’s preferences.
