JPEG:  (pronounced jay-peg) is a commonly used method of compressing photographic images.  The compression algorithm is "lossy" in that information is removed from the image to assist with shrinking the file size.  The greater the compression, the more information is lost.  Files that have undergone jpeg compression usually have extensions such as .jfif, .jpeg, or jpg.

The name stands for Joint Photographic Experts Group.  JPEG itself specifies only how an image is transformed to digital (a stream of bytes), but not how those bytes are encapsulated in any particular storage medium.  JPEG is the most common format used for storing and transmitting photographs on the World Wide Web.  It is not as well suited for line drawings and some other graphics because its compression method performs badly on these type of images due to loss of detail.

Most digital cameras also create files that are in JPEG format.  This is a testament to the popularity of the standard.

Pixel:  A pixel (the contraction of picture element) is any of the many tiny dots that make up the representation of digital images (i.e. patterns of dots) which are stored in a computer's memory or shown on a display monitor.

The number of pixels in an image is called the resolution.  The more pixels used to represent an image, the less visible the individual pixels will be and the closer the result will resemble the original (photograph, drawing, etc.).  Usually the dots are so small and so numerous that, when printed on paper or displayed on a computer monitor, they appear to merge into a smooth image.

Redeye: Redeye is the undesirable affect in flash photography of people having red eyes.  It is caused by the reflection of the flash from the retina.  Redeye removal is an editing procedure that eliminates this affect.

Resolution /dpi:   A digital photo is simply a grid of small picture elements known as "pixels".   Most digital photos contain millions of pixels, tiny bits of color or tone that combine to make a photograph.  Scanners read the color information from a photograph or piece of film and record this data a pixel grid.  The amount of detail captured by the scanner is known as resolution.  Resolution represents the amount of detail the scanner captures and is most commonly expressed as SPI (samples per inch), PPI (pixels per inch), or DPI (dots per inch).  For our purposes, we use the term DPI, though there is no practical difference among the three terms.  DPI tells you how many pixels (dots) per square inch captured by the scanner.  The higher the resolution, the more pixels the digital image will contain.  The more pixels a digital image contains, the more detailed that image will be.

TIFF TIFF format is the standard for most commercial and professional printing needs 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, and fax transmission.  TIFF saves detailed image information with each pixel resulting in a relatively large data file.
