Image resolution The number of pixels in a digital photo is commonly referred to as its image resolution.
Inkjet | A printer that places ink on the paper by spraying droplets |
| through tiny nozzles. |
ISO speed | A rating of a film's sensitivity to light. Though digital cameras |
| don't use film, they have adopted the same rating system for |
| describing the sensitivity of the camera's imaging sensor. Digital |
| cameras often include a control for adjusting the ISO speed; some |
| will adjust it automatically depending on the lighting conditions, |
| adjusting it upwards as the available light dims. Generally, as ISO |
| speed climbs, image quality drops. |
JPEG | A standard for compressing image data developed by the Joint |
| Photographic Experts Group, hence the name JPEG. Strictly |
| speaking, JPEG is not a file format, it's a compression method that |
| is used within a file format, such as the |
| common to digital cameras. It is referred to as a lossy format, |
| which means some quality is lost in achieving JPEG's high |
| compression rates. Usually, if a |
| JPEG setting is chosen on a digital camera, the loss of quality is |
| not detectable to the eye. |
LCD | Liquid Crystal Display: a |
| and/or rear of a digital camera to display settings or the photo |
| itself. |
Media | Material that information is written to and stored on. Digital |
| photography storage media includes CompactFlash cards and CDs. |
Megabyte (MB) A measurement of data storage equal to 1024 kilobytes (KB).
Megapixel Equal to one million pixels.
Memory Stick® A memory card slightly smaller than a single stick of chewing gum. Like CompactFlash and SmartMedia, it is
