Name 2 ways you can decrease depth of field - Answer✔1) Use a longer lens; 2) Move closer to
the subject
A lens set at f/4 admits how much more/less light than one set at f/2.8? - Answer✔Half as much
light
When buying a lens hood, you should get it in what size relative to the lens? - Answer✔It should
match the focal length. Too wide and it's inefficient; too narrow and it will vignette; most likely
to occur with wide angle of 28mm and below.
A color image with smooth gradiations requires at least what bit depth? - Answer✔24 bits per
pixel (8 per color), which gives 16,777,216 colors
When the size of the aperture is decreased, it is said to be what? - Answer✔stopped down
A general purpose lens will provide an f-stop range of up to how many? - Answer✔8 stops
Panning does what? - Answer✔Keeps a moving subject sharp while blurring the background
What is an element and where is it found? - Answer✔A simple lens with two curved sides or one
curved and one flat side; found in a compound lens.
What two controls adjust the amount of light that reaches the sensor? - Answer✔Aperture and
shutter
What do TTL systems react to? - Answer✔The amount of light reflected back from the subject
during exposure.
Convex lenses cause light rays to do what? - Answer✔bend toward each other and converge at
the focal point.
In short lighting, where is the main light placed? - Answer✔To strike the side of the face away
from the camera.
Why does a short lens create wide-angle distortion - Answer✔Because you can move in close to
the subject

What does ISO stand for? - Answer✔International Organization for Standardization
Aperture controls what? - Answer✔The brightness of the light that reaches the sensor
What is the suggested shutter speed to stop action of a child running parallel to the film plan,
about 25 feet from the camera? - Answer✔1/250th
Perspective is affected by what? - Answer✔lens-to-subject distance
What is a BYTE? - Answer✔An 8-BIT sequence that represents 256 possibilities - black & white
& 254 shades of grey. The size of a file is the number of bytes it contains.
Most modern lenses are based on this kind of lens - Answer✔Convex
Sharpness from near to far is controlled by what? - Answer✔Aperture
The quantity of light that reaches your sensor is controlled by what? - Answer✔Shutter speed &
aperture
The term to describe the combination of aperture and shutter speed that can be changed by
moving them in opposite directions - Answer✔Reciprocal relationship
Most lenses are sharpest closed down to how many stops from the widest? - Answer✔1 or 2
Name two ways you can increase depth of field (other than changing aperture) - Answer✔1) Use
a shorter focal length; 2) Move farther away from the subject
In a curves adjustment layer, what does the shape of the curve indicate? - Answer✔Contrast
When the additive primaries are mixed together equally, what is created? - Answer✔White
(additive primaries are Red, Green Blue)
An in-camera reflected meter reading a very dark scene indicates an exposure of 1/250th at f/8.
For a correct exposure, what should you do? - Answer✔Use negative exposure compensation
(underexpose). The meter will attempt to make the dark scene 18% grey, underexpose to bring it
back to dark.
When the subtractive primaries are added together equally, what is created? - Answer✔Black.
Subtractive primaries are Magenta, Yellow, Cyan
What is the inverse square law? - Answer✔The intensity of the illumination is inversely
proportional to the square of the distance from light to subject. At twice the distance from the
subject, the light illuminates only 1/4 of the original.
What is TTL? - Answer✔Through the Lens. A camera that can automatically control flash
exposure using sensors inside the camera.
If you must move to reduce the amount of flash reaching your subject, how far do you move? -
Answer✔To create a 1-stop difference, multiply the original distance by 1.4. Example - if you
were originally 5 feet away, a 1-stop difference would have you step back to 7 feet.
