Photography can be referred as being the process of creating moving or still pictures by means of capturing live data by observing radiations and storing it on sensitive medium similar to electronic sensors or electromagnetic film. 

The camera is simply an image forming device and the photographic film or electronic image sensors serves as its recording medium. In this modern time, good digital cameras for tweens have electronic medium that function as storing medium. As for the basic concept for cameras, it's controlling the amount of light and the time of exposure of the camera to the outer world by using the lens. We can generate an image on the film when there's enough light. The raw image may be developed in order 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 basic concept behind movie camera is that, the data are captured in series of photos without any delays in between them. For this reason, it is able to create a moving frame that's captured with the voice.

To make sure that we are only getting clear and sharp photograph, we have to be sure that we're adjusting the cam either automatically or manually. In the next paragraphs, you're about to learn camera controls with their short description. You can also visit this link if you are looking for GPS watches for kids.

Number 1. Focus - to bring the desired part or desired area to the sharpest point possible, this adjustment is very important. In most instances, this is manually done but in latest models of digital cameras, this can be done automatically.

Number 2. Aperture - as for this one, it can be referred to as adjustments of iris or otherwise known as the "f" number. This number is usually controlling the amount of light that's going to pass through the camera's lens. The aperture is meant 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 digital cameras that are used in ensuring that white light is captured as it's in real medium so by that, colors that are 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.
