cinematography Flashcards
(54 cards)
misen-en-scene is never by it self
photographing misen-en-scene
not only what it is but how it is presented in the filming
how is important as much as a what
how to communicate meaning through cinematography
tonalities
speed of motion
pespective
tonal control:contrast
ratio of dark to light in an image
high cntrast (big difference)
low constast(small differences)
used sometimes : tense,scary
used sometimes to demostrate : washed out,dreaming,vintage
speed of motion
rates calculated in frames per second (FPS)
24FPS-standards
film camera=flip book
perspective
depth of field and planes
planes
foreground(closer to us)
midground
background(futher for us)
how deep does our vision focus on a plane
depth of field
-deep focus(all planes are focused )
-shallow focus/selective
depth of field
what information is given to us
cinematography is not a proper miso-sene
contrast
comparative difference between the darkest and lightest
areas of the frame.
why is contrast important?
Contrasts in the image help filmmakers to guide the viewer’s eye to
important parts of the frame and to give the shot an emotionally expressive
quality—somber, cheerful, or whatever.
we control tonality with exposure
exposure: Exposure regulates how much light passes through the camera lens.
too dark (unexpose)
too light(overexposed)
The speed of the motion presented onscreen depends on two factors:
1.the rate at which the film was shot
- the rate of projection
If the movement is to look accurate on the screen, the rate of shooting should correspond to the rate of projection.
fast-motion
16-18
if exposed fewer frames per second then the projection it gives the effect of being speed up
slow motion
48-64
more frames per second slower the shot becomes
ramping
Varying the frame rate during shooting
perspective
The lens of a photographic camera does roughly what your eye does.
Located at a specific point, it gathers light from the scene and transmits that
light onto the flat surface of the film or video chip to form an image that
represents size, depth, and other dimensions of the scene.
the focal length
the distance from the center of
the lens to the point where light rays converge to a point of focus on the film
(this changes sizes,proportion and depths )
We can distinguish three general sorts of lenses, based on their focal lengths
and the ways they present perspective.
1.The short-focal-length (wide-angle) lens
2.The middle-focal-length (normal) lens
The short-focal-length (wide-angle) lens
-less then 35mm
-It’s called that because it takes in
a relatively wide field of view.
-lens exaggerates depth, making figures in the foreground seem unnaturally large and those in the distance seem quite far away
- The middle-focal-length (normal) lens
50mm
This lens seeks to avoid
noticeable perspective distortion.
Foreground
and background should seem neither stretched apart (as with the wideangle lens) nor squashed together (as with the telephoto lens)
- The long-focal-length (telephoto) lens
Long lenses take in a narrower angle of
vision than wide-angle or normal lenses do. As you’d expect, the effect
of movement with a long lens is the opposite of what happens with the
wide angle. A person moving toward the camera takes more time to
cover what seems to be a small distance.
