Today digital cameras have become an essential part of life. People use them at parties, weddings and other events to capture every important moment. They have the advantage that a photographic film is not required and images can be viewed instantly. However they have several features in common with the 35mm film type cameras. Both have a lens, an aperture and a shutter.
The lens focuses light to expose an image on a silicon chip, instead of a film. The aperture controls the amount of light that enters the camera and the shutter controls the length of time for which the light enters.
What Are Megapixels of a Digital Camera?
The number of megapixels is important for the quality of the pictures taken as it determines how much the picture can be enlarged. However, it is not the only factor to be considered when buying a camera. A 2 megapixel image can produce a good 5 by 7 print; a 3 megapixel, an 8 by 10 and a 4megapixel, 11 by 17. Manufacturers often print the megapixel number on the front casing, as it is the first thing buyers look for.
The High End Models
The more expensive digital cameras have advanced features and higher resolutions therefore they allow the photographer to be more creative. They have through the lens focusing, exposure control, shutter speed control and the ability to take multiple pictures rapidly in successive order. Such models appeal to the more serious photographers.
They are also models ranging from $1500 to $8000 and have resolutions up to 12 megapixels. Only the professional photographers can afford these as it is a huge investment. However, good news is that you can get a good digital camera for a whole lot less.
What To Look For In a Digital Camera?
A shopper should try out different models before buying one. This allows the purchaser to gauge how quickly pictures can be taken, how user friendly is the software of the camera and how easily the captured images can be viewed. The weight and size also have to be considered as they determine how portable the camera is. The weight can vary from 2.6 pounds to as low as 4.1 ounces. If a carrying pouch is not given with the camera it should be bought separately, as it allows easy travelling and prevents physical damage to the camera.
Batteries For The Digital Camera
The batteries used can be rechargeable; alkaline AAs or nickel metal hydride, or high capacity disposable CRV3s. The cost can range from $5 for four to $70 per piece. The choice depends on how much pictures the photographer wants to take. Advice can be taken from the seller or an online guide on batteries.
Few Additional Features In A Digital Camera
A buyer should always opt for a digital camera with an LCD display. That way pictures can be viewed right away, some discarded and repeat shots taken. A factor to keep in mind is to never buy a digital camera with floppy or compact discs. These discs are inexpensive but can store very few images. Also such cameras are bulky and slow.
The final choice depends on the shopper’s needs and the amount they can spend.
