What are IPTC fields used for? - ANSWER 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? - ANSWER 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? - ANSWER 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? -
ANSWER The diagonal measurement of the sensor.
What kind of light will be produced when using a large white umbrella close to
a subject? - ANSWER flat, low contrast light
This technique allows you to keep a subject that is moving toward you well focused -
ANSWER Follow focus
,How does 'unsharp mask' work? - ANSWER 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? - ANSWER 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? - ANSWER 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? - ANSWER Flattens out the volume of the subject
and minimizes textures
What kind of film can help reduce haze in a landscape? - ANSWER Infrared
Going clockwise around the color wheel, starting with RED, what is the progression
of colors? - ANSWER Red, Yellow, Green, Cyan, Blue, Magenta
Generally, traditional portraits use what lighting ratio? - ANSWER 3:1 or 4:1
An SLR camera uses what to allow you to see exactly what you'll photograph? -
ANSWER A mirror and pentaprism
What is a flag? - ANSWER 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? - ANSWER 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? - ANSWER Similar to a
normal lens at about 30 degrees
What angle of view does a spot meter read? - ANSWER Maybe as little as 0.5 degrees
or 1 degree
What angle of view does an incident meter read? - ANSWER Very wide at about 180
degrees
What is the name of the issue that prevents you from seeing exactly what the lens sees
when using a rangefinder camera? - ANSWER Parallax
What is the optical resolution on a scanner defined as? - ANSWER The pixels per inch
a scanner is capable of capturing often described as two numbers (i.e. 1200x2400)
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
