Digital Cameras - The Basics
Digital cameras have taken over the world. In a few short years they’ve pushed the 35mm film that was around for so long to the fringes of the market. If you’re about to plunge into this new exciting world of digital photography then there a few things you need to know to make sure your experience is a happy one.
Image MemoryIf you’ve used a camera before then there’s nothing different. You still point the camera in the direction you want and press a button to take an image. The image isn’t recorded on to film though it’s stored on a memory card. There are various card types available but the larger the capacity the more pictures it will hold. Image quality is dependent upon a number of things but one of the most important things to take into account is the CCD. The CCD is the part of the camera that captures the image. The more pixels on your CCD the more scene information is collected. The sensors are rated in megapixels so a 6 megapixel camera has roughly double the capacity of a 3 megapixel camera. The higher the number of megapixels the larger you’ll be able to print your images. Anything above 4 megapixels should comfortably print out a professional looking 6 x 4 postcard sized print.
MegapixelsThe megapixel count isn’t the only thing you should be looking at though as its only part of the story. Many digital cameras come with a zoom lens so that you can get closer to the action. Most of the cheaper compact cameras come with a 3x zoom so you get closer to the action but there are longer lenses available that get you even closer. The lens is one of the most important elements of the camera so choose carefully.
LCD ScreenAll but the very cheapest of digital cameras will have an LCD screen on the back so that you can see if the image you’ve just taken is any good. If it isn’t then all you have to do is delete the pic and take another. The larger the LCD screen the more of your picture you’ll be able to see. You can also use the LCD to preview your shot rather than squinting through the viewfinder.
