Photography Questions

How is a picture produced through conventional photography?
Traditional photography uses the action of light to cause changes in a film of silver halide crystals in which development converts exposed silver halide to (nonsensitive) metallic silver. Following exposure in a camera or other device, the film or plate is developed, fixed in a solution that dissolves the underdeveloped silver halide, washed to remove the soluble salts, and dried. How is a digital camera different than a conventional camera?
Conventional cameras depend entirely on chemical and mechanical processes -- you don't even need electricity to operate them. On the other h­and, all digital cameras have a built-in computer, and all of them record images electronically.
What are pixels and resolution?
Computerized images are made up of pixels, which are small squares of digital information with a color value. The number of pixels per inch needs to be associated with the dimensions of the image in order to give the image resolution. The more data that is recorded by a digital camera or scanner, the higher will be the resolution of the image file.
What are the specifications of the camera that you will use to take your pictures?
My camera is a Sony Cyber-shot, which has 10.1mega pixels, 4x zoom, and 1080 full hd still image.
What makes a picture a good picture? Give some tips for taking pictures.
Some things that make a good picture are whether it is in focus or no; whether it has been properly exposed, is it too light, too dark, or just right; whether it's clear what the subject is in the picture; whether the photographer made the best use of the frame; whether the photo can be improved by judicious cropping; and did the photographer notice and take advantage of leading lines, shapes, and textures. To take a good picture you just have to keep these things at the back of your mind.
What is a scanner?
A scanner is an electronic device that generates a digital representation of an image for data input to a computer.
What kind of scanner will you use to scan your pictures?
The scanner I will be using is a dell printer which can be used as a scanner.
How will you transfer pictures to the computer?
To scan a picture onto the computer, first you lift the top of the scanner and place the picture face down on the scanning glass. Then you close the top over the picture and press the "color" button under the setting "scan." The picture will scan onto the computer, and will probably show up under the program, paint. You can then take the picture out of the scanner and manipulate the copy of the picture on the computer as you like.
