Looking for a digital camera is quite a difficult task considering the numerous choices of cameras out there. Plus add all the buzz-words that has interpreted and even a short list of cameras that may be hard to analyze.
Digital images are composed of thousands or millions of tiny squares and each square possesses his own set of colors designated to it. When compressed or compiled, these colored squares makes images appear smooth once viewed at its original size. They are called Picture elements aka Pixels. The pixels only become noticeable when the images are magnified.
One million pixels is equivalent to one megapixel. If one pixel is converted to a megapixel, a camera produces images at a maximum resolution of 1600 by 1200 pixels; this is a 1.92 megapixel (1,920,000 pixels) camera. You should have higher megapixel of images if you are one who want to produce better prints of images. Higher megapixels do not necessarily mean better images, a common misconception. This is what they call megapixel.
The zoom of the camera is critical because you can take pictures from afar. The 2 kinds of zoom are Optical and Digital. Digital zoom uses circuitry. They make a portion larger than the standard sized image and they disregard the content outside the area zoomed. In contrast, Optical zoom works the same as the film on a film camera; it usually moves to make the subject larger. Practically, the optical zoom is more desirable.
The digital film or memory is correspondent to the film of old cameras. That there are two important things to remember when selecting a flash memory for your digital camera. One is to choose a quality module that can record quickly. In addition to that, it is instantly ready for the next picture – requires just a click. Second is the fact that the right format should be chosen.
Last but not the least is the connectivity. Most pictures taken in a digital camera needs to be transferred as a way for you to access them either onto a computer or to be printed. Cameras need to have a cable to connect to a computer also it can either be via serial, USB, USB 2. or Firewire. This way, you can view what you have captured.
There are things you need to look for when buying a digital camera. Aside from the megapixel and zoom, newer cameras even have smile detection and face detection pictures. By looking at the specifications, you will determine which brand and model of camera fits your needs.
