Midterm Flashcards
Angle of view
Focal size of your lens; produced by the lens
What affects light meter?
Angle of view
Vantage point
Produced by the image maker
Aperture
The physical opening of the lense
What does Aperture affect?
Exposure and depth of field
What is another name for aperture?
F-Stop and Diaphrams
Shutter Speed
Stops action and creates motion
What does shutter speed produce?
Exposure
What is ISO?
How sensitive the film is to light
Emulsion
light sensitive layer of the film or paper
Where is Emulsion?
Where the gelatin is in the silver halide
Latent
The exposed image not developed
Depth of Field
The amount of space that is in focus
Maximum Depth of Field
everything is in focus
What does Depth of Field Affect?
Aperture, Focal Length, and Camera to Subject Distance
What affects Exposure?
Shutter Speed, ISO, Aperture, and Light Source
What does Developer do to the film?
Speeds up the tarnishing process by converting silver halides to black metallic silver called grain and oxidizes the silver halide
What does Fixer do?
Makes film safe to light because it gets rid of the unused silver halides
What will the color of your film be if it is fixed properly?
Grayish Lavender
What will the color of your film be if it is fixed incorrectly?
Blue pink with white residue
What are two things to have a great quality negative?
Development and correct exposure
What are four variables in developing film?
Temperature, Time, Agitation, Dilution
If you do one or all things while developing film, what is the wrong thing to do if it gets underdeveloped?
If you give it to little time, under develop it, or too much water under diluted: under developed negative, opposite if you overdevelop it
What does light meter see the world as
Everything is middle gray (18% Gray)
How do you use light correctly to make a perfect exposure?
Subjects shadow, your own shadow, 18% gray card
What is F-stop to make it perfect?
F4
What is F-stop to make it perfect for print?
F8
Reciprocal relationship?
Give and you take. Aperture and exposure
How to read a negative?
Should be reading it with a bunch of different grays, some parts of images are dark and some are thin, white area are hilides, transparent converts to the dark areas which are the shadows
What do you do if your negative is denser?
Over develop it
Reticulation
Extreme change in temperature from one liquid to another
Why is reticulation bad?
It is bad because it shocks the film and the emulsion cracks
