Most salesman, emphasize on promoting megapixels the more, the better. This is simply a selling method and is not very true. We will explain why not. This is only a selling technique and is not always true. Let us understand why. The picture taken by a digital camera is constituted of a series of points called pixels. The more pixels make up that photo, the more details it can present; in other words, the more megapixels a digital camera delivers, the more you can zoom into the picture, or print in a big comfortable size, before it will get blurry and unclear. Imagine, for example, of a 10×10 inch mosaic and imagine filling it up with 2×2, 1×1 and 0.1×0.1 inch pieces and the more pieces you use, the greater the picture will be.
Because the cost of the digital camera increases with the amount of megapixels, you should first see for what you will use the digital camera for. If you will just use it to take shots for your website or probably won’t use to print pictures larger than a 5×7 there is no ground why you should go for something higher than a 4.0 MP camera. Keep your money for other stuff and add-on instead of investing in megapixels you will not use.
However, the main advantage you would get if you chose on spending more for a high resolution camera is cropping: a 9×12 picture taken at 5.0 megapixels can be resized to 8×10 and 5×7 without any problems.
Almost all present consumer cameras come with zoom possibility. This feature can be particularly useful when taking a picture of something that is too far away and you have no possibility to get near the subject, or you want to frame a portrait without taking much of the distracting surrounding. Optical zoom option is the proper magnifying characteristic, the digital camera enlarges the picture through an assembly of lenses before the image makes to the image sensor, and on the other hand the digital zoom magnifies the picture that is already saved in the digital camera.
Make certain you understood the camera’s technical specifications good. The total zoom is measured by multiplying the digital and optical zoom numbers. Make positive that the optical zoom meets your needs and don’t count on digital zoom at all, you can achieve its very same effect with any photo processing software.
We recommend you check out Canon SD880IS. But if Canon SD880IS is too expensive go for the cheaper Canon SD1100IS.
