Digital cameras seem to be taking over the photography world. While some people still appreciate the appearance of film cameras and the different developing techniques involved in processing film, most others have embraced the digital age.

Digital cameras rely on electricity and a microprocessor to convert analog signals into digital signals. To transmit information electronically, it must be converted into the digital form. For example, a cell phone takes the analog signal of our voice, changes it into digital, transmits the voice, then translates it back into an analog sound so that the other person can hear us.

A digital camera contains an analog translator called a charge-coupled device, or CCD. Another form of a CCD is a complementary metal oxide semiconductor, or CMOS. It is basically a sensor that takes in the light let in by your lens then coverts this into an electric signal. After the light is changed into electrons, the CCD or CMOS analyzes the charge of each cell of the device.

Although CCDs and CMOSes turn the different charges into pixels in dissimilar ways, they both turn the light from the image into electronic signals. Each discreet unit of electrical signaling is called a pixel. Pixel stands for picture (pix) element (el), and it stores the color, tone, hue, saturation, etc. of a single tiny piece of a whole photograph.

The more pixels a digital camera has, the less grainy a photograph will seem. If you have millions of tiny pixels, they all blend together into a harmonious image better than a few big blobs of color. Thus, a digital camera with a higher pixel count is typically considered better quality than one with fewer pixels.

Whether you choose to use a film or digital camera, photography is a great way to channel your creativity as well as save beautiful, long-lasting memories. Once you have an image that is worthy of display, you should consider turning your picture into canvas photo. For more information on this process, contact YourCanvasPhotos today.
