Digital camera technology is directly related to and evolved from the same technology that recorded television images.
In the digital world, data, or information, is represented by strings of 1's and 0's. In this case these digits translate to the individual pixels or basic units that combine to make up the image you see. When the capture button on the camera is pressed, a charge coupled device (also known as a CCD) creates an electron equivalent of the captured light which in turn ends up converting the pixel value into a digital value.
Digital cameras are rated in megapixels (millions of pixels). A 1.0 megapixel camera is considered not to be of quality while a 5.0 megapixel camera is often used in professional digital photography when creating studio grade portraits or taking pictures for a wedding.
Replaceable lenses are found on many higher end cameras. The good thing about them is that they increase the camera's versatility. There can be found: zoom lenses, close-up lenses, colour lenses for effects, and panoramic lenses.
data confirm that digital cameras could be very useful in monitoring climate change effects in forests: The results suggest that digital cameras can be an important aid in monitoring forests and the colour signals can be a useful proxy for photosynthesis. Not only forests, one could install this system or one like it at any long term monitoring site. Long-term ecological observation is now crucial for study in climate change and biodiversity. Digital cameras provide long-run evident footage with relatively low cost without labour.
