By now everyone knows the term “megapixels. This term is now used primarily to distinguish between the different digital cameras. In essence, the number of megapixels is a measure of resolution cameras. “Mega,” which means “millions” and “pixel” is a term that comes from the computer industry (which was first used to describe a resolution of your computer monitor) and comes from the words “image” and ” ; element “(Pix-EL). Thus, a 6 megapixel camera is equipped with a sensor consisting of 6 million picture elements.

Any digital camera is on the market today are highly automated, with automatic features for controlling exposure and focus. The days of cinema are gone, and now the images are stored on a memory card (flash memory).

You’ve probably noticed the huge number of cameras available and many different types. How do you choose between all the different megapixels, features, zoom, etc. Here are the 4 most important factors to make a decision on which one to purchase a digital camera.

Megapixels 1)

Try not to get too many megapixels on offer. Photographers While there are cameras available for the average consumer, with a maximum of 10 (and more) megapixel camera, the photographer normal or even more professional can be very satisfied with 7 megapixels.

More megapixels does not mean a higher-quality pictures. Other factors may be more related to image quality, as the lens and other features of the camera. More megapixels are needed only if you often collected and / or significantly expand their photos.

Capacity 2) to zoom

First, make sure you know the difference between optical zoom “and” digital zoom “. Optical zoom is actually done with the camera lens, while the digital zoom only enlarge the center of the image without having to increase the image detail. Over all cameras offer at least 3x optical zoom.

If you opt for more of this, the trade off might be the size and weight of the camera. The reason for the selection of a wider range of typical 3X zoom is that they often went to people who are at a distance of wildlife and sporting events.

More compact and sub-compact digital cameras have a zoom range greater than 3 times (some up to 7x). Super Zoom cameras typically have a greater zoom range of 10X. For SLR cameras zoom lens is entirely dependent on which is mounted on the camera. Most SLR cameras come with Ines to allow up to 3 times increase.

3) Full Control or automatic?

A compact digital camera is fully automatic and has at least a 3x optical zoom lens satisfies the needs of people in the camera and also the needs of the most serious photo enthusiasts. If you tend to take more pictures of sport and / or individuals, to wildlife and nature in general, you should focus more on digital SLR (DSLR) cameras.

The DLSRs offer greater flexibility in the selection of targets and manual functions that allow the photographer to manipulate the exposure time and aperture values. Also, digital cameras offer a wide range of ISO (light sensitivity I think) to allow shooting in low light standard compact digital camera.

Mark 4)

While many brands offer services at similar prices. However, some things to keep in mind that they are known in the community of photography, Kodak is at the forefront of offering simplicity and ease of use for the photographer, while Fujifilm offers image sensors with proprietary technology that delivers amazing picture quality . Canon, Nikon, Olympus offers an incredible range of cameras to suit every type of user.

Deciding on a digital camera can be tough with all the options available, but if you can decide on the 4 main criteria described here should make a decision much easier and more satisfying than it spent its money wisely.
