A reflex camera is one that utilizes a mirror system to reflect the light, and therefore the image, coming through the lens, to a visible screen. The image seen in the camera's viewfinder then is the same image entering the lens. This system provides the most accurate framing and focusing. Most reflex cameras reveal a high percentage of the image that will be photographed, upwards of 80%. Some reflex cameras are able to show 100% of the image frame into the viewfinder. The reflex system avoids the parallax problem that plagues most direct view cameras. See also SLR.

Refers to the number of pixels, both horizontally and vertically, used to either capture an image or display it. The higher the resolution the finer the image detail that can be seen.
Industry:Consumer electronics
A mechanism in the camera that controls how much light reaches the film.

The length of time the shutter remains open when the shutter release is activated, expressed in fractions of seconds.

A user looking through the viewfinder on this type of camera actually looks through the picture-taking lens, thanks to a series of mirrors and prisms within the camera. This is a very improved type of viewfinder, because what you see is what is in the actual picture frame.

Operating instructions for specific task based applications. The computer's processor carries out these instructions. Software has to be written for a specific computer Operating System (OS). Canon PowerShot digital cameras boast the most user-friendly, and advanced digital camera software bundles to date.

In this type of metering, a central spot of the frame is utilized to measure the light that is coming off the subject. The measuring spot is often indicated by the viewfinder of the camera. Used without care, this system can easily result in the metered area being well exposed while the rest of the frame is either under or over exposed.

The Tagged-Image File Format (TIFF) is used to exchange files between applications and computer platforms. TIFF is a flexible bitmap image format supported by virtually all paint, image-editing, and page-layout applications. Also, virtually all desktop scanners can produce TIFF images. This format of file uses the *.tif extension. The TIFF format supports CMYK, RGB, and grayscale files with alpha channels, and Lab, indexed-color, and Bitmap files without alpha channels. TIFF also supports LZW compression.

A positive photographic image,i.e. a slide, typically meant to be viewed by projecting light through the image.
Industry:Consumer electronics
Refers to a metering system that utilizes a light-sensitive mechanism within the camera body to measure exposure from image light passing through the lens. TTL viewfinders reveal exactly what the lens sees, avoiding parallax problems. See also Autofocus TTL.
