CPPS Exams Questions and 100 % Verified Answers
What do the bars on the left of a histogram represent?
Black (0)
What do the bars on the right of a histogram represent?
White (255)
The area of acceptable sharpness in an image is called what?
Depth of field
What is a derivative file?
A RAW file that has been altered
What kind of lighting pattern is useful to widen a subject?
Broad lighting
What kind of lighting patter is useful to narrow a face?
Short lighting
As the aperture is stopped down, what happens to sharpness?
More of the background and foreground are sharp.
Why is depth of field greater on a short lens versus a long lens?
Relative aperture. The opening on a long lens must be larger than a corresponding opening on a
short lens to produce the same f-stops.
What is focal length, technically?
The distance between the lens rear nodal point and the focal plane when the lens is focused at
infinity.
Focal length controls what?
,1) Magnification, or the size of the subject; 2) Angle of view
A normal (or standard) focal length lens approximates what?
The impression human vision gives
What determines what will be a 'normal' focal length lens on a particular camera?
Sensor size - the larger the sensor size, the longer the focal length of a normal lens.
(Corresponds to a diagonal line across the frame)
What does side lighting emphasize?
emphasizes textures
To minimize facial wrinkles, this type of lighting is best
Front lighting
What are IPTC fields used for?
Metadata fields that hold info on photographer, subject, and use.
An in-camera reflected meter reading a very light toned scene indicates an exposure of
1/250th at f/8. For a correct exposure, what should you do?
Use positive exposure compensation (overexposure). A reflected meter reading will attempt to
make the scene 18% gray - employ overexposure to adjust.
An incident-exposure reading for a fair-skinned subject reads f/8, 1/125th at 100 ISO. The
next subject is very dark skinned. What is the proper exposure for the second subject?
No change. The EXPOSURE doesn't change or it would also change the background as well.
Move the lights to adjust.
What is the general rule of thumb for the measurement of a 'normal' lens?
The diagonal measurement of the sensor.
What kind of light will be produced when using a large white umbrella close to a subject?
, flat, low contrast light
This technique allows you to keep a subject that is moving toward you well focused
Follow focus
How does 'unsharp mask' work?
It emphasizes the edges between tones. A threshold of zero affects all pixels - a higher threshold
affects just the edges with high tonal difference and minimizes noise.
What is the CCD or CMOS sensor?
The sensor that converts the image from analog to digital (1's and 0's) CCD=charge coupled
device; CMOS=complementary metal-oxide semiconductor
What does a neutral density filter do?
Absorbs equal quantities of all wavelengths of light. It allows you to use wider apertures or
slower shutter speeds without changing color balance.
What is the effect of front lighting?
Flattens out the volume of the subject and minimizes textures
What kind of film can help reduce haze in a landscape?
Infrared
Going clockwise around the color wheel, starting with RED, what is the progression of colors?
Red, Yellow, Green, Cyan, Blue, Magenta
Generally, traditional portraits use what lighting ratio?
3:1 or 4:1
An SLR camera uses what to allow you to see exactly what you'll photograph?
A mirror and pentaprism
