Most stores, both online and brick-and-mortar, emphasize on advertising megapixels as the main factor. 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 lot of spots named pixels. The picture taken by a digital camera is constituted of a lot of spots named pixels. The more pixels make up that photo, the better details it can present; meaning, the more megapixels a digital camera delivers, the more you can zoom into the image, or print in a big comfortable size, before it becomes blurry and unclear. Think, for example, of a 10×10 inch mosaic and imagine filling it up with 2×2, 1×1 and 0.1×0.1 inch tiles: the more pieces you use, the greater the quality.
Since the price of the digital camera rises with the amount of megapixels, you should first analyze for what you will use the digital camera for. If you will primarily use it to make shots for your blog or probably won’t use to print pictures greater than a 5×7 because of that there is no ground why you should go for something more than a 4.0 megapixel camera. Keep your money for other features and accessories instead of putting money in megapixels you will never use.
But, the main advantage you would get if you determine on spending more for a higher 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.
Most, if not all new digital cameras have a zoom feature. This option can be particularly useful when taking a shot of something that is too far away and you have no possibility to get close to the subject, or you want to take a portrait without taking a lot of the distracting surrounding. Optical zoom option is the real magnifying characteristic; the digital camera magnifies the image through an assembly of lenses before the picture comes to the image sensor, while the digital zoom magnifies the picture that is already saved in the camera.
Make certain you understood the camera’s technical specifications good. The overall zoom is measured by multiplying the digital and optical zoom figures. Be certain that the optical zoom meets your needs and don’t rely on digital zoom at all, you can achieve its very same effect with any photo processing software package.
One of the best digital cameras we can recommend is Canon SD880IS. But if Canon SD880IS is too expensive go for the cheaper Canon SD1100IS.
