The Beginner Buyers Guide To Digital Cameras, Or The Ins And Outs Of Megapixels.Warren Lynch The most important part of buying a digital camera is making sure that the one you select meets all of your needs. Digital Camera 101 Better digital cameras uses a chip called a "Charged Coupled Device" CCD instead of film. Light enters the camera, through the open shutter, and strikes the CCD where it is converted to digital data before being stored in the cameras memory. While that is the simple description, things can get pretty complicated from there. Megapixels & Resolution Resolution is a measure of how many pixels are used to make a digital copy of an image. Pixels are tiny dots of light that make up a digital image. The quality of a digital cameras image is usually measured in Megapixels where each megapixel represents one million pixels. Heres how to determine how many megapixels youll need depending upon the type of photos you will be taking and what you intend to do with them. 1 megapixel Almost obsolete, you might still find these in cell phones, PDAs, and desktop "web" cameras. Theyre OK if you only intend to email pictures to other people and those people arent going to be printing them. 1.1 to 2 megapixels Only slightly better than the 1.0, this resolution is OK for an average 4x6 snapshot, but it isnt going to be a production quality image. 2.1 to 3 megapixels This is the beginning of the decent camera range. You get very good 4x6 images and reasonably good 5x7 images. These cameras are low cost and provide a good platform for beginners. 3.1 to 4 megapixels You are qualified to say that you have a "pretty good" camera. You get professional quality 4x6 images, real good 5x7 and 6x9 shots, and somewhat decent, but not great 8x10 images. 4.1 to 5 megapixels and up People will be saying "Hey, great pictures!". You can count on professional images all the way up to 8x10s. Of course, as the megapixel count goes up, so does the price. If you are only going to be viewing your pictures online, such as posting them at a photo site or using them on your web pages, keep your money in your pocket and pick yourself up something in the 1.5 megapixel range. If you will be shooting pictures that will be printed at a print house, such as for brochures, postcards, etc, then you will need at least a 5 megapixel camera if not higher. Of course, youll also need to have a fat wallet or a lot of open to buy on your credit card because, even thought prices are steadily falling, these puppies arent cheap! Once youve solved the megapixel puzzle, the rest of a digital cameras features, such as lens types, storage capacity and shutter speed are pretty routine and easy to understand. You shouldnt have a problem deciding on those features. Join Photopheeds Daily Digital Dose and see Warrens Tips.
