...es be disastrous. Film is subject to the errors and inaccuracies of processing. The most common of these errors is crossover errors wherein the color shift of the highlights is opposite of that of the shadows (for example cyan highlights and reddish shadows). This occurs when one of the three light sensitive layers of the film (RGB) gets developed to a slightly different contrast than the other layers. The photographer cannot correct for this type of processing error with filtration. It can be fixed, with some real difficulty, in scanning by a skilled operator. Film has grain, which introduces noise and impurities into the image when scanned. The big difference between traditional film cameras and digital cameras is how they capture the image. Instead of film, digital cameras use a solid-state device called an image sensor, usually a charge-couple device (CCD). On the surface of each of these fingernail-sized silicon chips is a grid containing hundreds of thousands or millions of photosensitive diodes called photosites, photoelements, or pixels. Each photosite captures a single pixel in the photograph to be. When the shutter closes to end the exposure, the charge from each pixel is measured and converted into a digital number. The series of numbers can then be used to reconstruct the image by setting the colour and brightness of matching pixels on the screen or printed page. This makes printing a lot easier with the digital cameras. · You'll never have to pay for film or processing again. PROS · It's like a Polaroid on steroids: You can see your captured shot immediately. · From shooting the camera to posting on the Web to generating a print from your ink jet printer-the whole process takes only minutes. · If you don't like the shot you just took, you can instantly erase it and shoot it again. · Some digital cameras allow you to shoot videos or record and play MP3 sound clips, and some double as a Web camera. CONS · Digital cameras cost a lot more than comparable film cameras. · Generally, image quality may not be as good and the size of the enlargements may be limited because of the digital camera's resolution. · There's always a time delay from when you turn the camera on until it's ready, as well as from the instant you press the shutter and the picture is actually captured. · Digital cameras eat batteries, so you'll always be buying or recharging them. · It's difficult to see anything in the LCD viewfinder in bright sunlight. Photography as art is not effortless. At the start people believed photo to be no more than just captured image and as it developed people began to see just how much effort it needed. Photography as a social activity is simple With a quick touch of a finger and some help from a processing service, most of us can produce a snapshot good enough to be pasted into an album. Now with the digital cameras talking photos could not be easier no film, no darkroom, no bulky album full of snapshots. So if we make it easier for the artist then is that artist any less talented. From the first cameras artists have used them to help with there work. Man Ray was one of the first using cameras to take photos of his artwork, and then later on he would use it as a form of art. Painters are still using cameras to help them today Artist Lisa Walker writes “When I paint outdoors, I try to remember to take a couple of photographs of the...
