How many megapixels do I need on a digital camera, to get a good picture?
This really depends on what you want to do with the images. If you want to use a picture for PowerPoint presentations or view on a computer screen, then a 1 megapixel will be sufficient. This will also accomodate an image you want to project onto a screen (upto 8ft). If you want to print the images then the more the megapixels you have on the camera the clearer the picture will print. Currently 5 megapixels cameras offer a good quality level which will give sharp images on an A4 sheet.
