New digital cameras are coming out every day, new features, more zoom better picture and more mega pixels are some of the catch phrases that sound very familiar to anyone who has gone through any set of weekly flyers. There are so many different kinds of digital cameras to choose from. The most common issue that consumers interested in buying a digital camera are faced with is which one to choose and why. Many consumers are faced with many tough choices and sometimes due to misinformation they tend to over spend. Digital cameras are just one example where people tend to buy something with features they will never use, for no reason and spend extra money. In most cases digital camera buyers purchase expensive digital cameras that have features that they don't know how to use and will probably never use. It is like buying a Ferrari for daily trips to the convenience store. Nevertheless, problems like these could be easily solved with a little better information. In order to find a camera that best suites your needs you need to know a few things about digital cameras in general. The first thing and the most advertised way to distinguished from one type of digital camera to another is the number of mega pixels that camera has. The more mega pixels the better the camera is. More mega pixels mean better resolution for your photos. Every computerized image is comprised of thousands of little coloured dots called pixels. A mega pixel is equivalent to one million pixels. Therefore, if a camera has more mega pixels the photos have better resolution. Most people just want to buy the best and go for the cameras with the most mega pixels. The truth is that if you are not going to blow up your pictures in larger than poster size frames then you don't need a camera with more than 6 mega pixels. Most professional photographers have cameras that are less than 8 mega pixels. But then again you see people who are new to photography carrying cameras with 10 mega pixels. In general however, more mega pixels mean that if you enlarge a picture, you would get more detail and clearer colors. Another important characteristic of a camera including a digital camera is the zoom. Most digital cameras out there have both digital and optical zoom. The optical zoom is the zoom on the lens whereas the digital zoom is done by zooming in digital on the already digitized image. A higher optical zoom is always better than a higher digital zoom and in other words means that the camera has a better lens.. Digital cameras are usually furnished with optical of between 3x to 10x. After the lens and the resolution cameras differ from each other based on the memory they have. Memory meaning how much data they can store. Each photograph, depending on its resolution is stored as data on a memory stick or a USB drive. The more memory your camera has the better it is because you will be able to store more photos. Although there are different kinds of memory cards you should find one that is again better for your needs. There are larger cards as well as faster cards. If you are going on a trip and you want to take photographs of your family then buy a large and slow memory card. Professional photographers and photojournalists prefer fast memory cards so they can transfer their photos faster and take more. It all depends on what you are going to use your digital camera for. The key point to find the best digital camera is to find one that will best fit you and your lifestyle and your needs. Don't just buy the latest or the one that claims they are the best digital cameras out in the market, don't over spend for features you will probably never use. Buy a digital camera that you think is best for what you need it for, and remember, just like with everything else there are always ways to save money when buying a digital camera.
