Palette. A thumbnail of all available colors to a computer or devices (much like an artist's palette). The palette allows the user to choose which colors are available for the computer to display. The more colors the larger the data and the more processing time required to display your images. If the system uses 24-bit color, then over 16.7 million colors will be included in the palette.
Panorama. This means capturing a series of images to create a picture wider than what you could capture in a single image, by "Stitching" the photographs together. Needs special software to allow and help you do this.
Parallax. An effect seen in close-up photography where the viewfinder does not see the same as the lens. This is normally due to the offset of the viewfinder and lens. This is not an issue if you are using the LCD as a viewfinder or if your camera is an SLR..
PC. In camera terms it denotes a type of flash synch connector, popular on most film and high end digital cameras. Otherwise, it means Personal Computer.
PictBridge. This is a new standard for direct USB printing from digital cameras to inkjet and dye sub photo printers. It does not need the use of a computer.
PIM. (Print Image Matching). Epson's new standard of embedded color and printing information for digital cameras. Many of the camera manufacturers have joined with Epson and now embed the PIM information in the Exif header of the JPEG images created.
Pin-Cushioning. This is a common geometric lens distortion causing an acquired image to pucker toward the centre of the image, usually found at telephoto focal lengths.
Pixel. The individual imaging element of a CCD or CMOS sensor, or the individual output point of a display device. This is what is meant by the figures 640x480, 800x600, 1024x768, 1280x960 etc., when dealing with the resolution of a particular digital camera. Higher numbers are best.
Pixelization. The stair stepped appearance of a curved or angled line in digital imaging. The smaller the pixels, and the greater their number, the less apparent the "pixelization" of the image. Also known as the "jaggies".
Polarizer. (Polarising Filter). A filter for eliminating glare and reflections which attached to the front of your lens (normally just SLR's). Just like your polarized sunglasses it will get rid of glare, the polarizer filter does the same for your digital camera. There are 2 types of polarising filter, linear and circular. Linear is for film only, it screws up most auto focus systems on digital cameras. Therefore be sure you use a circular polarizer filter. It can also be used to darken skies and increase the saturation of colors.
PNG. (Portable Network Graphics). This is an image file format. It is a compressed file format similar to JPG.
Point and Shoot. Term used for a simple, easy to use camera with a minimum of user controls. The camera does everything automatically so you literally just point and shoot..
PPI. Pixels Per Inch. A measurement to describe the size of a printed image. The higher the number the more detailed the print will be.
Pre-Flash. Some digital cameras use a low power flash before the main flash to automatically set the exposure and white balance.
Programmed AE. The camera chooses the best shutter speed and aperture automatically.
Prosumer. Refers to more expensive semi-professional digital cameras aimed at a consumer market.
