used in Illustrator; resolution independent; defined by mathematically defined lines and curves (paths); limited colors
|
|
resolution-independent
|
can be scaled up/down to any size without changing their visual appearance
|
|
bit depth
|
the number of bits used to define a pixel; determines maximum number of colors that can be displayed at one time
|
|
24-bit color (True Color)
|
assigns 8-bits of data to each of the 3 color channels used in RGB color
|
|
Image compression
|
a mathematical way of saving file space by taking an image and compressing the file size without reducing the visual quality
|
|
image resizing
|
uses resampling; reconstituting the image matrix; make an image larger/smaller without losing anything
|
|
downsample
|
resize smaller
|
|
upsample
|
resize larger
|
|
cropping
|
involves getting rid of information; no resampling, just cutting an image

|
Main things to photograph

the placement/arrangement of visual elements/ingredients in a work of art, as distinct from the subject of a work
|
|
Field of View
|
the portion of the scene visible through a particular lens. ; the visible area of a scene that's composed within a frame
|
|
wide shot
|
establishing shot
|
|
close-ups
|
the bread and butter of photos; pulls people into the picture
|
|
Focal Length
|
the distance from the optical center of the lens to the film plane; determines the lens' angle of view
|
|
Aspect ratio
|
The relationship of the width of its frame to its height
|
|
4:3
3:2 16:9 |
TVs and most cameras
some cameras cinema |
|
orientation
|
shooting in landscape or portrait mode
|
|
angle of view
|
the relative position of the camera below or above the subject
|
|
low angle
|
a sense of power & confidence
|
|
high angle
|
conveys a sense of weakness & vulnerability
|
|
eye level
|
used with journalism; makes things unbiase and at a fair level
|
|
Subject Placement
|
the position of the subject relative to other elements in the frame
|
|
mergers
|
the interaction of foreground and background elements within the frame
|
|
Rule of Thirds
|
the intersection points are the most powerful parts; avoid dividing image equally horizontally/vertically; center is weakest place for subject
|
|
Depth of field
|
how much of the scene across the z-axis is in focus; shallow vs. expanded
|
|
Six Basic Elements of Design
|
Lines, Shape, Form, Texture, Pattern, Color
|
|
Lines
|
horizontal/vertical, diagonal, converging, s-curves, leading lines
|
|
diagonal lines
|
add visual interest
|
|
converging lines
|
lead viewer into the picture
|
|
s-curves
|
guide eye through the scene
|
|
Shape
