non-lossy (aka lossless)
    A term that refers to data compression techniques that do not remove image data details, to achieve compression. this method is generally less effective than lossy methods in terms of reducing fil...
f-stop (aperture)
    A term used to describe the aperture, or diaphragm opening of a lens. f-stops are defined numerically: f/1.4, f/5.6, f/22, etc. larger, or wider apertures, allow more light to enter the lens, whic...
aps-c (apsc)
    A term used to describe the size of the digital imaging sensors used in almost all compact dslrs. the name is derived from the aps (advanced photo system) film format that was introduced in 1996 f...
cmos (complementary metal oxide semiconductor)
    A type of imaging sensor, cmos chips are less energy consuming than ccd-type sensors and are the dominant imaging technology used in dslrs. although once considered an inferior technology compared...
non-volatile memory
    A type of memory card that retains data when power is turned off. camera memory cards (compactflash, sd, smartmedia, etc.) use non-volatile memory.
    A type of rechargeable battery that was originally developed for use with camcorders and is now used as a power source for most digital still cameras and camcorders.
