There is so many makes and models from digital camera like Canon, Nikon, Olympus, Pentax, Sony, Panasonic and others this makes the process of buying or choosing the digital camera a very hard, time consuming and frustrating. When you choose a digital camera the most important thing to check on it is the megapixils, because its determine the quality of the pictures, but there is another things you have consider when buying a digital camera which are cost, resolution, exposure control, type of memory card, and batteries.
In the beginning decide how much you are ready to pay for a camera. You will more than likely find what you are looking for within almost any budget minus certain features, of course.
The most important thing to decide is the resolution its hard to determine the resolution that you need. A digital photograph is made up of thousands of pixels (little squares); the more pixels per inch, the better quality the photograph. A megapixel is the term used for a million pixels - and the more megapixels an imaging sensor has, the higher the camera's potential resolution. According to amount of money you are ready to spend on the camera you well choose the resolution. The more resolution camera the more money you have to spend the higher resolution camera you can buy.
Now you have to think about the exposure control, exposure control is the next big decision when purchasing a digital camera. Exposure values may seem a little frightening, but you can pretty much assume you'll have the basic assortment of meter modes. Most extended zoom cameras offer full exposure controls, so you can customize settings to fit your preferences. These modes help the camera determine the correct exposure for tricky compositions, such as a backlit subject.
Then consider the type of media card your camera will use. Media Cards can be called the storage or memory card that stores the images until you load them to your computer. Those that use proprietary card formats are often more expensive and less available than more standard card types such as Compact Flash or SD/MMD cards. If your digital camcorder and PDA all use the Secure Digital memory card, this may be a major deciding factor when buying a digital camera. Why buy a digital camera with a different format when you can switch the card with electronics you already own? When considering memory cards, you should buy the largest capacity you can afford: the higher capacity cards, while expensive, are cheaper than buying two cards of the next-lower capacity.
Digital cameras consume a lot of power so it's better to choose a rechargeable battery than the AAA ones. Finally, don’t forget to get the battery charger and a couple of sets of batteries.
The basics of choosing a digital camera are to know your budget, know what type of pictures you want to take and how you intend to use the pictures. Consider the type of memory card your new camera will use and the type of battery. If you follow these simple rules you should have a much more pleasant buying experience.
