Enter, Digital Camera
November 8th 2006 19:41
My good and longtime friend received his brand new Nikon D80 today, and even I must admit, from a non-photographer perspective, that it's a nice looking little camera.

You can also view my friend's photography on his deviantART page.
If you take a photo with your digital camera, light bounces of your subject and enters the camera through the lens. Because it is a digital camera, the photo has to be digitized. This is the process whereby the light waves that enter your camera, is translated into a language a computer can understand, called bits. These bits form long strings of 1’s and 0’s, which are broken down into tiny dots of color, called pixels.
A normal analog camera has a piece of film inside that captures the light when the shutters quickly open. Similarly, a digital camera has a sensor that converts light into electrical pulses.
The amount of detail a digital camera can capture is called resolution, measured in pixels. That’s why it’s important that the mega pixels your camera can take on are high enough.
The interesting is that the sensors are colorblind – they only measure light intensity. Filtering is used to filter the light into the three primary colors: blue, red, and green. High quality cameras have a filter for each of the primary colors, and use a beam splitter to split the image so that each one of the filters receive equal amounts of light. Because of the filters, it only responds to that particular primary color. The camera uses these three colors to create any other color in the color spectrum.
What’s nice about a digital camera is that the photos are all stored on a flash memory card. This makes accessing the photos obviously very easy – no more photo labs, just plug in into your PC and voila!
After all the excitement I shared with my friend today, I’m thinking of getting myself a digital camera (but that’ll have to wait until my bank account allows it.)

Perhaps you can take it as a research and see whether any compact digital cameras are able to perform basic SLR features?
