DESCRIPTION

At its very simplest description, a digital camera is a camera that does not record photos on film. However, in order to be able to do that, a digital camera requires a whole new system inside. There is nothing that a film camera and a digital camera have in common, except for the lens and the fact that it will record images.

Digital Cameras Are Already The Future Of Photography

At its very lowest level description, a digital camera is a camera that does not record photographs on film. However, in order to be able to do that, a digital camera needs a whole new system inside. There is nothing that a film camera and a digital camera have in common, except for the lens and the fact that it will take photos.

A film camera depends on chemicals that react to light to make colour photographs, but a digital camera has millions of small sensors that record the colour that they 'see' on a chip, so that they may get accessed later.

A film camera does not require electricity unless it has a motor drive, but a digital camera may not operate without electricity, which is normally supplied by batteries. The better the camera, the more power that it will require.

Apart from these technical details of internal parts, the biggest difference between a film camera and a digital camera is in the composition of the photos. Because a digital picture is made up of dots known as pixels which are recorded digitally, they can be manipulated by a computer program.

A conventional film photo may not be modified after it has been 'fixed', but a digital photo can be manipulated at any time. You just load it into a photograph manipulation program such as Photoshop and you will be able to change all the yellows to green, brighten the lighting, sharpen the image, alter the contrast and a hundred more things.

As with all new technology, digital cameras used to be very expansive, but the price was soon recouped because there was no requirement to buy film or have it developed into photos. This is a big saving. However, the price of digital cameras has dropped so much that the technology can be put into mobile telephones without dramatically raising their price.

The main thing to look for whilst buying a digital camera is the resolution, which is expressed in terms of megapixels - the number of dots that make up the picture. The more the better. At the time of writing, ten megapixels is around regular, but a professional DSLR camera might have 35 plus megapixels.

A digital camera needs a memory in order to store the pictures. The memory comes in two varieties akin to with a computer - it has on board RAM and a slot for an external memory chip, normally known as a flash card.

It is best to have lots of internal memory but it is not vital if you use flash cards. The cards come in various sizes. The more megapixels your camera has, the more memory your camera will require.

If you want better than a point-and-click camera, consider purchasing an SLR or in this case a DSLR - a digital single-lens reflex camera. These cameras permit you to swap lenses for extraordinary effects like fishbowl look, telephoto or macro photographs. A DSLR camera with a basic lens will be about $550 so will not break the bank, but will permit you to take professional quality photographs.
