Reading this article will give you the information you need to choose a Digital Camera based on the functions and features that it has. It’s a Digital Camera buying guide that will tell you what you need to know. In many ways, cameras with 35mm film are the same as the modern Digital Camera. In both cases you will find a shutter, an aperture and a lens inside.
The major difference between these two types of cameras is the method they use to get the image. Digital Cameras use an image sensor instead of film to capture it, and normally it’s a CCD (charge couple device). These are silicon chips that have millions of pixels, which are photosensitive diodes). Each one of these pixels gets one small part of the entire photo. Once the shutter is opened, those pixels get and record the light’s brightness. When the shutter is closed again, the recordings from every pixel are converted into a number. The Digital Camera then rebuilds the image using those numbers, doing a lot of calculations (millions of them) to reconstruct the photo.
When you use a film camera the photo will be stored on the film. But, Digital Cameras need to use another device to keep photos on them. After the image sensor captures the photo, it will be kept on a storage device inside the Digital Camera.
If you own a Digital Camera, you can view the photos you take on an LCD screen that you can find on the camera’s back. You can take photos with ease, without carrying film with you. Store everything on memory cards instead!
The great thing about Digital Cameras is how easy it is to use and distribute to other people. Just a few examples: use email to give them to friends, upload them to a site or use them in a word document.
An even bigger difference from film cameras is the fact that you can also record movies and sound with the latest Digital Cameras.
A few of the biggest features that Digital Cameras have
When you decide to buy a Digital Camera, there are a number of features that you need to know about, and the most well known is the resolution.
The Resolution
The camera’s resolution tells you the number of pixels that are on it. When you know how big is the megapixel number, you know how good the camera is (when the number of megapixels is big, the resolution is big as well).
Different megapixels lets you make different size prints. If your camera has 1 megapixel, you can create a 4×6 inch print. A camera that has 1.5 megapixels will allow you to create a print that is 5×7 inches in size. This continues the same way, with the big megapixels allowing you to create bigger prints.
