  3. Movin’ on Up Terms • Bounce Light – light reflected off a card or wall • CMYK – Cyan, magenta, yellow and black color world used in printing • Color Balance- the process of compensating for too much of one color in an image (if an image is too blue, yellow is added to bring the image back in balance

  7. Movin’ on Up Terms • Firewall – software program or hardware set to protect a computer from outsiders wanting to steal info • Fixed Focus Lens – a lens preset to one range of distance • Focal Length – distance form the midpoint of the lens to the convergence point on the film plane; determines whether it is telephoto, wide or normal lens

  8. Movin’ on Up Terms • HSB – hue, saturation and brightness • HSL - hue, saturation and lightness • Hue - color • Index Color – the act of reducing color available to fit a smaller range of colors; done to reduce file size

  9. Movin’ on Up Terms • Jaggies – stair stepped pixels on diagonal or curved parts of an image. • Key Light – main light source • LPI - lines per inch; a measure of resolution on a printing press • Mask – a layer or selection of a file used to protect a portion of an image

  10. Movin’ on Up Terms • Noise – unwanted artifacts in an image • Normal Lens – a lens that has the same focal length as the human eye • Saturation – purity or intensity of color • Shade – gradation of color with reference to its mixture with black

  11. Movin’ on Up Terms • Sharpness – refers to focus and the ability to display detail • Speed – the sensitivity of film or a chip to light • Tone – value, brightness or lightness; the amount of light a color reflects • Zoom Lens – a multiple focus lens
