film characteristics (4)
|
(1) film speed (2) grain (3) tones (4) contrast
|
|
|
light sensitive __________ ___________ crystals
|
silver halide
|
|
|
the higher the film speed the more ________
|
grain (the film is grainier)
|
|
|
latent image
|
the image of the subject that forms as an invisible pattern of altered silver halide particles in the emulsion. Chemical development converts the film's exposed silver halides to black particles of metallic silver, making the image visible.
|
|
|
contrast
|
the difference between dark and light tones (in the original subject or in the negative and print represent the subject).
|
|
|
focus length and angle of view
|
Example:
17mm = wide angle of view / 1000mm = narrow angle of view (close up) |
|
|
all lenses control or affect these basic functions: (4)
|
(1) focus (2) film exposure (3) angle of view (4) depth of field
|
|
|
choices for depth of field: (2)
|
(1) aperture (2) how close you are to subject
|
|
|
the more light you let in
|
the depth of field shrinks (aka the more shallow the depth of field)
|
|
|
aperature
|
an opening that allows light into the camera
|
|
|
image distortion
|
light rays hit glass and bend too much stretching the image
|
|
|
depth of field: (3)
|
(*1) lens aperture (*2) distance to subject (3) lens focal length
|
|
|
shutter speed controls ___________ of subject
|
appearance
|
|
|
shutter speed controls appearance of subject
|
faster = freezes it
slower= blurs it |
|
|
exposure factors (4)
|
(1) subject lighting (2) lens aperture (3) shutter speed, and (4) film speed
|
|
|
Stops (3)
|
(1) A doubling or halving of light.
(2) Usually indicates a change in aperture. (3) Each full stop adjustment is called one stop. |
|
|
Equivalencies (2)
|
(1) "There is no ONE way to get the correct exposure"
(2) A different combination of shutter speed and f/stop. |
|
|
f-stops

|
|
overall darker scene
|
under expose (film gets less light)
|
|
|
overall lighter scene
|
over expose (film gets more light)
|
|
|
BRACKETING
|
taking light reading shot (+) under exposed (+) over exposed
|
|
|
colored filters
|
create contrast in subject colors that render as the same gray tone in black-and-white
|
