Digital Envisions

The camera market can be a confusing one to any new comer who has got no idea about the things that make up a good camera. If you are unaware of the factors that govern the picture quality of a camera then you might as well end up getting swayed by the words of the salesman and end up purchasing something that costs a decent fortune but feels unsatisfactory in performance.

Some of the factors that govern the picture quality of a camera include aspect ratios, megapixels, Sensor size, ISO settings and many more. Not all of these are important to understand in order to make a decent camera choice, rather a trivial knowledge of a few such as zoom type, ISO settings and sensors, megapixels are more than enough to get a good first time camera. Using just a bit of information on each you can make up your mind as to what will be best for you.

The first consideration that you may already be aware of is the megapixels of the camera. A camera that quotes 4 megapixels means that its pictures have a total of 4 million picture units in it. In layman’s terms the more the megapixels the more detailed a picture. However, detail is not all that determines if the picture is good. Without having a means of capturing a good picture, how it is stored hardly matters. However, the rule is that more megapixels the better the image.

The sensor and its ISO ratings determine the quality of the picture captured. Most entry level cameras come with the smallest sensors and the lowest ISO ratings often providing on the least ISO 100 level. These cameras cannot take pictures under stress conditions such as low lighting, fast moving etc. As the sensor size and its ISO rating increases it is able to take more sensitive shots. The sensor to digital camera is as to the reel to a lens camera. This is why DSLRs cost so much because of its better ISO rates and bigger sensor chips.

The zoom type confuses many into picking the digital zoom over the optical zoom on the criteria that more the zoom better the magnification. True but, magnification counts for nothing if it is not with clarity. Optical zoom does not reduce picture quality whereas digital zoom eats away at picture quality with every level of extra zoom. Optical zoom cameras are always better than digital zoom ones.

Depending on your budget you can choose the best combination of all these factors and make a decent choice even though you are shopping for a digital camera for the first time. The only actual limit that you will be putting on yourself is the budget.
