Why do some cameras have an LCD screen and a viewfinder?
Generally, it’s easiest to frame shots using your camera’s LCD screen. Sometimes, though, glare from the sun makes it difficult to compose pictures on the screen. That’s when having a traditional viewfinder is a great bonus. And when you frame shots with your viewfinder, you can steady the camera against your cheek, helping to prevent accidental camera shake and blurry pictures. Taking pictures using the viewfinder instead of the LCD screen also saves battery power. While digital SLRs have an LCD screen for reviewing photos, you’ll normally use the viewfinder to compose shots with this type of camera. However, a new trend has SLRs including live view LCD screens, on which you can frame pictures just like you would with a point-and-shoot camera.
