The link that Safetymom posted will give you all of the commonly used abbreviations for Disney-related stuff.
But since this is the photography board, how about if we start a list of the photo-specific abbreviations, which are not on the general abbreviations list?
I may get some of these a little wrong, so those with more photographic experience may feel free to correct any screw-ups I make!
SLR = Single Lens Reflex - the type of camera with detachable lenses. A mirror inside reflects light from the lens up to the viewfinder; this mirror has to pop up out of the way when the iris opens to let light travel straight back and strike the film or sensor.
DSLR = Digital SLR - an SLR camera that shoots digital pics instead of film
AF = AutoFocus
MF = ManualFocus (no, not that other thing! This is a family board!)
ISO = International Standards Organization - Film speeds are measured with increasing numbers on a standard scale approved by ISO, so 400ISO means film that has a speed of 400 on the ISO scale. The ISO scale is based on the older ASA (American Standards Association) scale.
DPI = Dots Per Inch - A measure of the resolution of digital scanners and printers. Sometimes mistakenly applied to the digital image files created by scanners and digital cameras.
TTL = Through The Lens - A type of exposure metering, mostly used in SLR cameras, basically meaning that the camera measures the amount of light that actually comes in through the lens, usually giving a more accurate measure of how long and how wide the camera's iris will need to open to properly expose the film or sensor inside.
CCD = Charge-Coupled Device - a type of sensor used in digital cameras in place of film to record an image. Used mostly in more expensive, higher-end cameras.
CMOS = Complimentary Metal-Oxide Semiconductor - another type of sensor used in digital cameras. Cheaper to manufacture than CCDs and they use less power, but more succeptible to noise in the images.
