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.
A picture can be stored in many levels of detail which is determined by the megapixel count of the camera. A camera with higher megapixels means that it can store more picture information in one shot. Hence, if a camera boasts of a 3 megapixel, then it means that every shot it takes will have 3 million picture units in it. However, just going by the megapixels when choosing a camera, is not wise.
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.
Many people think confuse digital zoom as being better than optical zoom simply because one can get a large amount of zoom with digital. This is completely false. An optical zoom is an all natural zoom that does not crop images whereas digital zoom does its job by cropping and magnifying the image digitally which results in a loss of quality.
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.
