Question

If you increase the number of megapixels on a camera do you get a better picture?
I know that you just cant increase them but is it true that the higher number of mega pixels the better the camera or is that complete and utter crap

Answer

Its true up to a point. For normal size prints, it doesnt matter if you use or megapixles the prints will look the same. But with more megapixels you can make better enlargements. For a full page print, youd want megapixels. For a small poster, youd want megapixels.brThen theres the lens. Most point amp shoots have pretty average lenses. These lenses only send about megapixels worth of information to the sensor so if you have a megapixel sensor, the rest is simply wasted. To take full advantage of a megapixel sensor, you need professional quality lenses. You can only get professional quality lenses for digital SLR cameras however. These are each. Often even .brAnd finally, in low light situations, having more megapixels can actually reduce image quality!! Every pixel corresponds to a photosite on the sensor. The more megapixels, the smaller the photosites, and the more light they need to do their job. In low light sitiations, youd want fewer but big photosites instead of tons of super tiny ones.brSo megapixels just says something about how big you can print. Image quality is determined much more by the quality of the lens.
