Art 2060 Final Flashcards
Define aperture
size of hole light passes through
Write out aperture values
1, 1.4, 2, 2.8, 4, 5.6, 8, 11, 16, 22, 32
What does a smaller number of aperture mean?
A smaller number means a larger aperture and creates a shallow depth of field.
What does a larger number of aperture mean?
A larger number means a smaller aperture and creates a deep depth of field.
Define shutter
Time open
Write out shutter values
1 1/2 1/4 1/8 1/15 1/30 1/60 1/125 1/250 1/500 1/1000 1/2000
What does a bigger shutter value mean?
A larger shutter value is a longer shutter speed and allows more light into the camera and creates more motion.
What does a smaller shutter value mean?
A smaller shutter value is a shorter shutter speed and allows less light into the camera and creates less motion
What does ISO measure?
ISO measures sensitivity to light
Write out the ISO values
100 200 400 800 1600 3200 6400 12800
What does a smaller ISO value mean?
A smaller ISO value means less sensitive to light, better on bright day
What does a larger ISO value mean?
A larger ISO value means a bigger number and more sensitive to light, better in dark room
What are factors that affect depth of field?
aperture, distance to subject/focal length (zoom), distance from subject to background
What factors effect motion?
shutter speed, camera movement (panning), subject movement (speed), distance to subject (closer=faster)
What are the six qualities of light?
Comparative qualities (color, brightness, contrast) Formative qualities (specular, diffuse, direction)
