photography midterm
There are two primary variables that control how much light reaches the image sensor or film plane, one is aperture and the other is _____________.
Shutterspeed
A light meter which measures the light as it travels through the lens of a camera is called a:
TTL meter
The craft of photography is embodied in the control of what steps needed to create a photograph?
Technical
What is the focal length?
The distance between the lines in the center. Changes when you bring the subject in the focus, measured in millimeters
Digital zoom?
The lens does not do anything special. Picture goes into the camera maximum optical zoom. The camera Stabley S-t a digital data resulting in a loss of quality.
What is exposure?
The level of brightness of a shot.
Optical zoom?
Uses lens of the camera to establish the zoom. The lens act like a magnifying glass
Shutter speed?
Way to control amount of light getting in, the longer the shutters open, the greater the level of exposure. How slow or fast the camera's shutter opens- controls the length of time the sensor is being exposed to light
The hottest color temperature?
blue
The choice of shutter speed has a direct effect on all of the following EXCEPT:
depth of field
Hazy conditions represent a +1 BEF (Basic Exposure Formula). If our normal exposure is f/16 @ 1/125, which exposure below would be correct for hazy light conditions?
f/11 @ 1/125
If f/16 @ 1/30 is normal exposure for ISO 100, which exposure would be normal for a quicker shutter speed change to 1/60 of a second?
f/11 @ 1/60
Of the following f/stops, which would allow the most light into the camera?
f/2 Yes, f/stops represent fractions. The larger numbers let in less light than the smaller numbers, therefore f/2 (or 1/2) is definitely larger than f/32 (1/32). This fraction represents the diameter of the lens opening in relationship to the lens in use (ie., with a 50mm lens f/2 would have a diameter of 25mm).
If f/2.8 @ 1/500 sec was determined to be the correct exposure, then what would be considered an equivalent exposure?
f/2.0 @ 1/1000 sec
Depth of field (DOF) will be greater with which exposure combination below?
f/22 @ 1/30
If f/11 @ 1/125 is my exposure, which exposure combination below is a good equivalent for a portrait? (Remember, you will want the background out of focus.)
f/5.6 @ 1/500
It is noon and the light conditions are normal overcast. If my ISO is 100 and I want to keep my original shutter speed, what f/stop should I use for a correct exposure in normal overcast?
f/8
A lens with a wide maximum aperture is called a:
fast lens
Catchlight
highlights in the eyes- gives the subject life
Diffused Light
light is created when light is scattered and comes from all directions. It is softer and does not cast harsh shadows
Direct Light
light strikes the scene from a specific direction, creating highlights and shadows. It can be dramatic and harsh
To let twice as much light in to the camera it is necessary to open up the lens how many stops?
one
The coldest temperature color?
red
Which factor does not immediately control depth of field?
shutter speed
exposure
shutter speed, aperture, ISO
The International Standards Organization rates the ________ of a digital camera sensor or traditional film.
speed
When information to make an exposure is gathered through light hitting a small circle in the center of the viewfinder this is called:
spot metering
Rule of Thirds
the frame or view is divided into thirds both horizontally and vertically, and important pictorial objects or subjects are placed either on one line or at the intersection of two lines. Helps create a balanced & interesting composition and emphasize the subject.
Resolution
the sharpness and fine detail in an image the higher the ppi, the higher the resolution or sharpness of the image300 ppi is good for making a print.72 ppi is good for the Web.
Aperture/ F-stop?
the size of the opening of the lens. how small or large the opening of lense is- controls the amount of light entering the lens and striking the sensor
Which of the following does not 'control' the exposure?
the type of meter used
A reflective meter would read a white building as 18% grey.
true
F/5.6 is one stop from f/8 on your lens and it allows twice as much light to strike the image sensor plane than f/8 allows.
true
F/5.6 lets in 2 stops less light as compared to F/2.8; or 1/4 as much light to the image sensor or film.
true
The Golden Mean refers to harmonious proportions
true
The shutter speed has an effect on camera shake.
true
What is the BEF compensation for open shade on a bright sunny day?
+3 BEF
The light conditions are heavy overcast (+3BEF). I am shooting a film camera and my film speed is ISO 125. To establish a darker 'mood', I would like to create a -1 exposure from normal (a one stop underexposure). Which exposure below would be correct?
1/15 @ F/22
