Once captured, digital photographs are already in a format that makes them incredibly easy to distribute and use. With many cameras you can immediately see your images on a small LCD screen on the back of most cameras, or you can transfer the images to your PC and from thereon the possibilities are endless.
If you're considering going digital, here are a few reasons to get there faster.
- Digital cameras save money in the long run by saving the cost of buying rolls upon rolls of film and paying for their development. (Simply put digital photography is instant photography without the film costs!)
- Digital cameras save time because you don't have to make two trips to the store to drop off the rolls and then pick up your developed pictures.
- Digital cameras instantly display your pictures so you'll no longer have those "disappointments/shocks" a day or two later when your film is developed.
- You can view images before they are printed and if you don't like what you see, edit them to perfection or delete them.
- No more waiting to finish a roll before having it processed. (Or wasting unexposed film when you just can't wait.)
Digital cameras are very much like the familiar 35mm film cameras. Both contain a lens, an aperture, and a shutter. (The lens brings light from the scene into focus inside the camera so it can expose an image. The aperture is a hole that controls the amount of light entering the camera. The shutter opens and closes to control the length of time the light enters). The big difference between traditional film cameras and digital cameras is how they capture the image. Instead of film, digital cameras use a solid-state device called an image sensor. On the surface of each of these fingernail-sized silicon chips is a grid containing hundreds of thousands of photosensitive diodes called pixels. Each captures a single pixel in the photograph to be.
