Digital Camera - What is all in megapixel

The photographs that you take with the camera actually consist of a vast amount of dots in different colours. If you zoom into a picture you will see the image break up into a collection of dots, which when viewed normally will appear as a good image. These dots are known as pixels, so if you have a lot more pixels in the same image then the detail will be clearer and you will be able to print a larger photograph without it becoming blurred. A megapixel is a million pixels, which would be good enough for a decent image. If you are looking for something to print a good A4 photograph then about 4 or 5 megapixels is more than adequate. There are digital cameras with resolutions of 12 or 15 megapixels, but these are definitely over the top. What you see is limited by the limit of your eyesight, so unless you wish to make wallpaper for your living room then the higher resolutions are unnecessary.

Think of mega pixels the same as dots per inch on your TV.The more dots the better the picture,same for mega pixels. For digital photography more pixels means you can enlarge a photo,and print it at "Best Quality"

I have studied about megapixels and here is what i got. In one sense, megapixels of resolution is an awfully arbitrary way of dividing up the camera market. (And it's just the sort of fixation on a single parameter (resolution) that I tend to rant about.) It does amount to a useful way of sorting out and narrowing down the range of cameras you're looking at though. Once you've got it down to megapixel groupings, it's fairly easy to separate out beginner/intermediate/advanced groupings from there.

I dont know much about digital cameras but i think the clearity of the camera picture depends on the number of pixels it has. so more pixel, more quality photo
