and Answers;(Certified Professional Photographer Exam

What is a BIT?
The smallest unit of information consisting of either a 1 or a zero. It can only represent
two possibilities - either yes or no, black or white.
What is a color profile?
A mathematical translator assigned to each piece of equipment you use (they map one
gamut to another; and the ICC (or International Color Consortium) profile is usually
shipped by the equipment manufacturer).
What is gamut?
The entire range of colors that can be seen, reproduced, or captured. Our eyes have a
greater gamut than a print or monitor.
How can you change the brightness of the background when using flash?
Change the shutter speed. The longer the shutter speed, the lighter the background will
be. The faster the shutter speed, the darker the background will be because less
existing light is captured.
What is interpolated resolution?
Interpolated resolution can be generated by Photoshop or any image editing software to
increase print size resolution.
Digital cameras use what set of primary colors?
Additive (R, G, B)
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 pattern is useful to narrow a face?
Short lighting
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 of human visual perspective
, 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 on a subject or surface?
emphasizes textures
To minimize facial wrinkles, this type of lighting is best
Diffused front lighting
What are IPTC fields used for?
Metadata fields that hold info on photographer, subject, and usage.
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
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
An SLR camera uses what to allow you to see exactly what you'll photograph?
A mirror and pentaprism
What is a flag?
Also called a gobo; it is a small panel usually mounted on a stand that shades some
part of the subject or shields the lens from light that could cause flare
A filter with a factor of 2 requires how many stops of compensation?
factor of 2 = 1 stop compensation. (Each time a factor doubles, it's one additional stop)
What angle of view does a reflected light meter read?
Similar to a normal lens at about 30 degrees
What angle of view does a spot meter read?
Maybe as little as 0.5 degrees or 1 degree
