So you bought a new digital camera and now you want to know how to use it. Well luckily you have found this digital photography tutorial. This product photography tutorials should give you a basic understanding of digital photography.

The first thing to understand about your new digital camera is the way that it captures images. Most cameras work on the same basic principle. There is a aperture in the front of the camera that lets in light, the CCD at the back of the camera (a light sensitive surface), and the shutter that sits between the aperture and the CCD. When you push the little button on the camera to take a picture, you are releasing the shutter to open for a fraction of a second to allow light to expose a light sensitive microchip that converts the light that hits it into information that can be saved in digital format.

Even the simplest camera usually allows you to independent control the aperture, the shutter speed, and the light sensitivity of the CCD (CCD stands for charged coupling device and is the digital equivalent of film). The aperture, shutter speed and light sensitivity of the CCD are linked must be balanced like an equation. The CCD has a very specific amount of light that it needs to be exposed properly. You can control the amount of light that hits the CCD by opening and closing down the aperture and speeding up or slowing down the shutter. Most camera will do this automatically for you, but for the adventurous, you can usually take control of these attributes.

The aperture is measured in F-stops and has a number like F22. The larger the F number the smaller the opening for light to enter the camera. The larger the F number, the larger the depth of field of the shot. For instance, if you take a picture of a flower in front of a mountain with a high f-stop, both the flower and the mountain will be in sharp focus. However if you take the same picture with a low f-stop, and focus on the flower, the flower will be in focus and the mountain will be pleasantly blurry. Taking photos with a low f-stop is a great way to take portraits.

You can also control the speed of the shutter. The shutter speed is usually measured in fractions of seconds like 1/2000. So if you are taking pictures of the neighborhood football game you want a fast shutter to get those sharp action shots. A slower shutter lets in light for a longer time. This is great if you want to capture the feeling of the flow of a fountain, for instance. Be careful with using slower shutter speeds without a way to stabilize the camera, as a slower shutter speeds allow for any little move of the camera to be captured in the image.

Now go out there and use this digital photography tutorial to capture your memories with style.
