Digital Cameras Are Already The Future Of Photography
http://the-real-way.com
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, besides the lens and the fact that it will record images.
A film camera relies on chemicals that react to light to create colour photos, but a digital camera has millions of small sensors that record the colour that they 'see' on a chip, so that they can be 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 delivered by batteries. The more powerful the camera, the more power that it will require.
Apart from these technical details of internal components, the biggest difference between a film camera and a digital camera is in the composition of the photos. Because a digital photo is made up of dots known as pixels which are recorded digitally, they may be manipulated by a computer program.
A conventional film picture cannot be altered after it has been 'fixed', but a digital photo can be modified 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 photograph, alter the contrast and a hundred more things.
As with all new technology, digital cameras used to be very expansive, but the cost was soon recouped because there was no requirement to purchase film or have it developed into photos. This is a big saving. However, the price of digital cameras has fallen so far that the technology can be put into mobile telephones without radically increasing their price.
The main thing to look for while buying a digital camera is the resolution, which is expressed in terms of megapixels - the number of dots that create the photograph. The more the better. At the time of writing, ten megapixels is about normal, but a professional DSLR camera might have 35 plus megapixels.
A digital camera needs a memory in order to store the images. The memory comes in two forms like with a computer - it has on board RAM and a slot for an external memory chip, usually known as a flash card.
It is best to have lots of internal memory but it is not essential if you use flash cards. The cards come in different sizes. The more megapixels your camera has, the more memory your camera will need.
If you would like more than a point-and-click camera, think about purchasing an SLR or in this case a DSLR - a digital single-lens reflex camera. These cameras allow you to swap lenses for special effects like fishbowl look, telephoto or macro photos. A DSLR camera with a standard lens will be about $550 so will not break the bank, but will allow you to take professional quality photographs.
