 1. A camera operates in a simple way. Images come through lenses and react to light; images are then stored electronically in some fashion. 2.  Important Factors to Purchasing a Camera:  a.  __Megapixels__ – stem from lithographs which consist of little dots. This is similar to pixels, which are just one portion of a photograph; these dots mix together to create the colors in photographs. i. The higher the number of megapixels you have, the better the photography will be. ii. The higher the number of megapixels, the larger the file will be. This will make downloading and storing more difficult and time consuming. b. Colors c. Price d. Size 2. Three types of cameras: a. __Point and Shoot Cameras__ – i. These consist of cell phones and very cheap cameras. The normally cost under $150. ii. They are simple to use and don’t have many options. b. __Prosumers__ – i. These cameras are around $500-700. ii. They are considered to be middle of the road. c. __Professional Models__ – i. These range from $1,000 – 3,000.  ii. These do not come with lenses, so this adds to the expense of the camera.

3. Connections: a. __USB Cables__ – i. This is one of the simplest connections. ii. This is not included with the camera, and are often very hard to obtain for simple cameras. b. __Fire wire__ – i. These are exceptionally high speed and are normally used for video cameras. c. __Wi-Fi and Bluetooth__ – i. These are wireless connections

4. Storage Systems:  a.  __ Memory Cards – __ i. Do not touch the metallic piece, because the grease from your fingers will deteriorate the interior of your camera. ii. These consist of SD Cards, XD Cards, and even CDs. b. __Hard Drives__ – i. These are normally pre-set and on the cheapest models of cameras. There is no way to add more space to the hard drive. 5. Two Types of Zoom: a. __Optical Zoom__ – i. This actually zooms in before the picture is taken. b. __Digital Zoom__ –  i.  This happens after the picture is taken; it is digitally redone based on the setting you put in. 6. Shutter:  a.  This automatically focuses the picture for you once you have the button pushed half way done. b. These are often color coded with green, yellow, and red.

7. Aperture:  a.  This has to do with the amount of light allowed to enter the lens.  b.  This consists of settings such as night vision. 8. Software:  a.  These allow you to edit photographs and view them online.  b.  Some examples are: i. Picasa ii. Photoshop iii. iPhoto
