-
4 factors of exposure…
- 1-aperture
- 2-shutter speed
- 3-film speed
- 4-amount of light
-
Camera’s main function
view the scene you selected
-
film records...
the image transmitted by the lens
-
viewfinder
shows the picture that the lens focuses on the film
-
shutter
opens and closes to control the length of time that light strikes the film
-
aperture
adjusts the amount of light reaching the film
-
Film speed describes a film’s...
sensitivity to light
-
diffusion
scattered, not all coming from the same direction such as sunlight on a cloudy day
-
smaller the aperture size...
more that a scene will be sharp from near to far
-
What affects the amount of light entering the camera and the sharpness of a photo?
shutter speed and aperture
-
define a shallow depth of field
specific abount of sharpness
-
difine a deep depth of field
everything in focus (pinhole camera)
-
Depth of field:
the part of a scene that appears sharp in a photo AMOUNT OF ACCEPTABLE SHARPNESS
-
3 ways to make a shallow depth of field
- Shallow
- Closer to the subject
- Wide apperture
- Long focal length
-
3 ways for a deep depth of field
- small aperture
- short focal length
- far from subject
-
stop of light:
measure of light
-
f/stop is the same as an:
aperture
-
if you over expose your film then...
it is too light
-
Exposure:
how much light is allowed to hit the paper, film or digital or sensor
-
Developer:
activates the exposed silver crystals
-
Stop bath:
mild acid bath and stops action of develop
-
Fixer:
removes the unexposed silver crystals and makes image permanent
-
ISO/film
speed refers to the sensitivity to light for the film
-
grain
refers to the size of silver crystals
-
Enlarger printing
- 1.Put negative you want in negative carrier, emulsion side down
- 2.Fix it’s aperture and enlarger for good focus
- 3.Make a test strip, starting with filter 2
- 4.the test strip is not right go up or down for a new contrast
- 5.With the right, filter make a test strip again with 20, 15, 10, and 5 seconds
- 6.Choose which would look best
- 7.Then make enlargement
-
Balance/emphasis/contrast is related because...
they rely on each other to make the contrast of gray, to balance it out and emphasis the picture. Contrast creates the emphasis and the balance makes it look right
-
Shape:
an object, any object, that may have a 2-D image
-
Form:
3D and encloses volume with width, height, and depth
-
Dodging
makes parts of a print lighter than other parts
-
Burning
makes selected parts of a print darker
-
Shutter speeds:
- 1000
- 500
- 250
- 125
- 60
- 30
- 15
- 8
- 4
- 2
- 1
-
Compositional devices:
- -simplicity
- -fill the fame
- -rule of thirds
- -framing
- -perspective
- -leading lines
- -repetition/rhythm
-
Robert Capa famous quote:
“if your pictures aren’t good enough, you aren’t close enough.”
-
Spot/line-
a spot/line helps viewer see the main point better and eye connects to 2 spots at once
-
contrast attracts__________
attention
-
camera angle can__________a subject
emphasize
-
in film speed a higher # is more...
sensative
-
hand holding cameras sutter speed
1/60 or faster
