Why do I need a digital camera for? This is the first question a buyer would have to ask himself before making the purchase.
Leaving out the obvious advantages of the digital cameras (large storing capabilities, the speed, the LCD, the possibility of photo processing, the absence of consumables like film and photographic paper) the future owner of such a device needs to consider carefully what he will use it for.
Is the camera bought for a vacation or trips with the family and friends? Is it destined to go artistic? Is the buyer looking for a semi-professional camera, or is he a professional photographer ready to make the big step into digital world?
After answering this question the hunt for your camera can begin.
There are two major types of digital cameras in the market. The “Point and shoot” types are the classical digital cameras.
They can be classified as compact (and have certain under-divisions such as ultra compact) and bridge cameras with super zoom (that are making the passage to DSLR-s).
They are operated by using a sensor (CCD or CMOS) to emulate the photographic film (catching the photons) and the image resulted in the lenses is projected on the LCD.
The size of the sensor is mainly responsible for the quality. It is good to know that the size of the sensor does not give the number of mega pixels especially in the new types of camera (the ones manufactured after 2004).
The best digital cameras from the “point and shoot” category come with a series of additional options like recording movies, capture play backs, etc.
The DSLR –digital lens reflex cameras are the equivalents of SLR-s using film and have objectives (mechanical ensemble and tubular) changeable. The light catching principle is appreciatively the same, meaning that they use the same CCD or CMOS sensor but this type of camera uses a mirror in order to return the image in a real time.
The sensor functions only during exposure and this is how the delay of the “point and shoot” camera is eliminated, and the image is reproduced in a real time frame. The speed of catching the light is higher and the moving objects can be caught without blurring.
A real DLSR does not make movies and does not have an EFV (electronic view finder). This types of cameras, even if sold as DLSR are just bridge cameras.
A DSLR requires a higher amount of attention and carrying than a typical digital camera and it also comes with a much higher price. This type of camera is not recommended for the beginners in digital photography and it is usually purchased and used by professional digital photographers.
These are the cameras used for artistic photography and they need a formed eye and a skilled hand to handle them.
