color model
a way of mixing base colors to create a spectrum of colors
HSL
hue, saturation, lightness
00:02
01:22
HSB
hue, saturation, brightness
gamut
the whole range or extent
additive method
A solid modeling design method where geometric primitives are combined to create a single object.
subtractive method
method of diminishing the wave lengths of light by superimposing two or more color transparencies over the same light source; the light is gradually reduced by absorption of colors in the light.
Raster images
are often called bitmap images because they are made of millions of tiny squares, called pixels
Bitmap
an image composed of pixels with a fixed resolution
bit depth
Refers to the number of colours in an image.
true color
24-bit color depth
Deep color
A color depth that uses a bit depth of 48, which produces over 1 billion colors.
Alpha Channel
Part of a pixel's data that tells how opaque or transparent that color should appear when the graphics card calculates how to render the image on screen.

01:22
Masking color
A single shade of a color that can be set to be transparent.
vector images
Use mathematic equations and geometric elements (points, lines, and shapes) to create art.
Bitmap tracing
"The process of software programs that also convert raster images to vector images
Optimizing
picking the very best option
Compression
The part of a longitudinal wave where the particles of the medium are close together.
Lossy Compression
a process of reducing a file's size by altering and/or eliminating some pixels
dithers
Breathing holes in the image or pixels are no longer touching each other
Interpolation
A passage included in an author's work without his/her consent
dots per inch (dpi)
A measurement of image quality for printers.
Pixels per Inch (PPI)
A measure of screen density refers to the number of device pixels on a physical surface.
resampled
Reads a new image without reducing the image resolution
bicubic
produces a better quality than either nearest neighbor or bilinear; the processing time takes a little longer, and a more complex method is used to determine the color of new pixels that are added based on a larger area of surrounding pixels.n:
