Mega Pixel
What is the functioning of megapixels, optical zoom and digital zoom in a digital camera.?
What is the functioning of megapixels, optical zoom and digital Zoom. Which of these should be more important. Which body should look for good quality night shots.
First, I feel is the optical zoom The importance of zoom function. I you can zoom in on the object by adjusting the lens, with minimal compromise on quality. Digital zoom, but is not very useful. I never use. Digital zoom is basically digitally crop the image by a portion and then she stretched. Since there are only so many points in this area if They pull apart, the end result will probably be a very rough idea, and hell lot of noise. Not very ideal. A common misconception is that the higher the megapixels, the better. This is not quite right. The megapixels do not need to tip, but is not high enough. Megapixels is the clarity of the picture, only to a certain extent. If the MP is very, very low, like 1, the image resolution will be low and data will not be covered. However, if the MP is too high, any additional Pixels just different than noise. Great offers high megapixel resolution, so that you blow up the picture. That is all. For beginners, 7 megapixels is more than enough so good that you can print A4 sized images.
