Midterm Flashcards
Pixel (3 things)
discrete unit, cannot be broken down into smaller units
- location, can not be changed, xy coordinate on a cartesian grid
- value(the luminosity of an image, colour), based on the colour data a pixel has been assigned to them
Pixel Array
Y axis x X axis = total number of pixels (important for resolution)
codec
compression + decompression,
- what colour information can we take away to make the file size smaller
interpolation
(animation or photoshop) asking the pixel information to be invented information around the original image (creation of pixels that don’t exist, uses master pixels to make up new pixels)
2 Ways to think of resolution
- quality of an image (image resolution)
- size of our screen (screen resolution) rhas a resolution of 750 x 1334
colour
- there is no colour on a computer, just a series of 1’s and 0’s and how the computer interprets them
- it exists in colour to control how my any colours you have available to you and what colours are being displayed to you binary - on or off
Additive colour
(what we work in on the computer) RGB, to make white, CMYK secondary colours
Subtractive colours
(pigment based) RYG as primary colours to make black
Hue
actual colour
PURITY
chorma, intensity, saturation
VALUE
luminosity, shade, tint
luminance
measure of the light in a hue
PAL
phase alternating line, 25fps
NTSC
national television standards commitie, 30 fps
process printing/laser printing
CYMK printing, ink will have to be applied 4 times
offset printing
physical ink, rollers are inked and plates are inked to print
workflow
the way in which you work, setting up the markers in which you will create a project
halftone
the reprographic techniques that simulates continuous tone imagery through the use of equally spaced dots of varying size at far enough distance, it looks continuous (printing vs screen)
DPI
dots per square inch (dots must go in lines) (printing, subtractive colour)
PPI
pixels per square inch (screen) (light, additive colour)
