The size of the opening in the lens also known as f/stop. ( a smaller aperture has a bigger f/stop number--lets in less light) The numbers represent ratios of the lens focal length to opening. The focal length is how long the lens is in millimeters. So f/2 is a wider open aperture than f/16 because the numbers are fractions.

Depth of field is like focus. It's the distance between the closest and farthest points in an image. Objects in an image that are closer are more clear and objects that are farther away are unclear and fuzzy.

Shutter Speed:
Shutter speed is the length of the exposure time or how long the shutter is open. Photographers change the shutter speed to catch objects that are moving.

Noise:
Noise is the random speckles of color, when there shouldn't be any. Noise can also be called grain because of the little grains of color.

 Histograms are very useful tools that show the tone range in a graph, like shown above. The higher the graph goes, shows the amount of pixels that tone has.

Mode of operating a camera that allows multiple snapshots to be taken in a single click of the shutter. 

[[image:white_balance.jpg]]
The process of removing unrealistic color casts, so that objects which appear white in person are rendered white in your photo.

Self timer:


A device that delays the tripping of a camera shutter so that the photographer can be included in the photograph.

Pixels:
The term "pixel" is actually short for "Picture Element." These small little dots are what make up the images on computer displays, whether they are flat-screen (LCD) or tube (CRT) monitors.

Auto Focus vs Manual Focus:
VS

Auto-focus usually provide better photo quality than fixed-focus, since auto-focus lenses can be larger and allow more light to reach the camera sensor. The downside of auto-focus is usually a delay when taking a photo (shutter lag). VS
 * Manual focus** disables the [|camera]'s built-in [|automatic focus] system so you can [|focus] the [|lens] by hand (*). **Manual focus** is useful for low [|light], [|macro] or [|special effects] [|photography].

ISO (international standardization organization):


ISO 9660 standard defines a file system used by [|CD-ROM] media. CDs formatted using this standard can be used on any [|operating system] that supports the ISO 9660 standard, including Windows, Mac, and Unix systems.

File Format:
.tiff: [|Industry-standard] [|method] for storing scanned and other [|digital] black-and-white, grayscale, and full-color [|images]. [|Developed] mainly for [|desktop publishing], TIFF has found applications in several other areas such as [|computer aided design (CAD)], medical imagery, fax transmission. TIFF saves [|detailed] image [|information] with each [|pixel], resulting in a relatively large [|data file]. .jpeg: [|Standard] for [|variable] [|compression] of black-and-white ([|gray scale]) and [|full] color still [|images]. Named after the [|committee] that wrote the [|original] standard, its file name carries the [|extension] 'jpg' or 'jpeg.' Unlike [|graphic interchange format (GIF)] [|files], which can show only 256 [|colors], JPEG can show 16 [|million] colors and is more suitable for photographs, naturalistic [|artwork], and similar [|material] than for [|line drawings], lettering, and simple cartoons. It [|provides] decent image [|quality] at great [|reduction] the final image may be as small as 2 [|percent] of the original. Being a lossy [|format] (see [|compression algorithm]), it loses a [|degree] of detail (which may not be obvious to the [|user]) depending on the degree of compression. Although some [|versions] of JPEG allow from 24-bit losless compression (usually 2:1) to a smaller bit-size [|lossy compression] (up to 60:1), the recommended [|ratio] is between 25:1 to 35:1 for everyday [|graphics] [|work]. JPEG is the most popular image compression format on the [|internet], and has a related standard (MPEG) for moving images.
