Which of the following lenses has a variable focal length?
a.) Zoom
b.) Not this one
c.) Not this one either
d.) Soper lens - ✔✔Zoom lenses zoom. When people say "Zoom in!" they're talking
about manipulating an action of the lens.
And the soper lens is a contact lens because of course it is.
Depth of field is defined as: - ✔✔The distance range within which objects are at a level of
acceptable focus.
As a general rule, the depth of field covers:
a.) A field width equal to 1/2 that of the human eye
b.) The entire field visible through the camera
c.) 1/2 behind and 1/2 in front of the point of focus
d.) 2/3 behind and 1/3 in front of the point of focus - ✔✔d.) Just remember that the depth of field
is greater behind the point of focus than in front of it. That's why the mountains in the background of
a snapshot can look in focus but your thumb in front of the lens will be blurry.
, The larger the f-stop number:
a.) The smaller the depth of field
b.) The larger the depth of field
c.) A wider depth of field
d.) The more resolution in the photograph - ✔✔B. The larger depth of field.
There's a lot of physics involved in this and I can't even begin to remember it all but just remember-
1.) Small f-stops have large apertures, shorter exposure times, and lesser depth of field.
2.) Large f-stops have small apertures, longer exposure times, and greater depth of field.
At an f-stop setting of 16, which lens will give the greater depth of field? - ✔✔Short focal
lengths correspond to greater depth of field. Wide angle gives the greatest, telephoto gives the
smallest.
In addition to being affected by f-stop and focal length, depth of field depends on:
a.) Film speed
b.) Whether the film is color or monochrome
c.) Distance from camera to subject
d.) Shutter speed - ✔✔C.) Distance from camera to subject
A deeper depth of field will result directly from all of the following except:
a.) A lens with a short focal length
b.) A higher f-stop setting
c.) A faster shutter speed
d.) A longer camera-to-subject distance - ✔✔C. Shutter speed does not affect depth of field.
Stop trying to make shutter speed affect depth of field.
The term synchronization means that: - ✔✔The shutter and the flash are synced, or synchronized,
to act together.
