|---|
| static array | digital cameras that capture the image in one fast exposure - suitable for action shots |
| linear array | digital cameras that capture the image using a longer scanning exposure - suitable only for still life compositions |
| studio digital camera backs | highest quality digital cameras that combine the front of a traditional camera with a digital back |
| single lens reflect digital camera | most common professional digital camera using many of the same lenses found in traditional 35 mm cameras |
| consumer digital cameras | lowest priced digital cameras - use same type of lenses as "point & shoot" cameras |
| studio resolution | pixel dimensions of 6000 x 7500 which capture a total of 45 million pixels' worth of data |
| professional resolution | capture just 3000 x 2000 pixels for a total of 6 million pixels |
| consumer resolution | range from 640 x 480 pixels up to 1200 x 1000 pixels - useful for only smallest print areas |
| binary | method for working with numbers based on only two digits 1 and 0 |
| lossy compression | JPEG compression software |
| pixel | hundreds of thousands of spots of light that compose a computer monitor |
| pixelation | condition where each pixel in an image becomes visible due to low resolution |
| resolution | density of dots or pixels on a page or monitor |
| archive | long-term storage of data or images |
| bitmap | image made up of dots or pixels |
| calibration | act of adjusting the color of one device relative to another |
| CD | compact disc - laser encoded plastic medium designed to store a large amount of data |
| CMYK | color encoding system used by printers for combining primary colors to process a color image |
| contrast | measure of rate of change of brightness in an image |
| digital camera | device that captures an image so it can be downloaded to and manipulated by a computer - filmless camera |
| flash | supplies auxiliary light to supplement natural or available lighting conditions |
| JPEG | lossy compression format that reduces the file size of an image |
| TIFF | raster format that is the best for files that will be transferred between Windows and Macintosh platforms |
| EPS | used generally as a vectory format, but sometimes as a raster |
| media card | memory device which stores photos in a digital camera |
| optical zoom | sharpest zoom on a camera - mechanical involving two pieces of glass |
| digital zoom | type of zoom which digitally enlarges a portion of an existing photo |
| always flash | can override the automatic flash causing camera to flash with every exposure |
| never flash | can override the automatic flash to prevent flash |
| slow 1/slow 2 | special flash which will enable you to take artistic photographs |
| 2.1 megapixels | fine for small photos no larger than 3 x 5 |
| 3.1 megapixels | handle photos without pixelation and blurring to 5 x 7 |
| 4.0 megapixels | print our clear photographs up to 8 x 10 |
| 5.0 megapixels | allow prints up to 16 x 20 |
| auto focus | automatically focuses on the object selected in the view finder |
| maco focus | allows you to focus 6 - 10 " away from the camera |
| spot meter | takes exposure reading of what is in the square and not the whole photo |
| infinity setting | focuses on infinity - good for distant objects |
