Unit 1.6 Flashcards
What is hyperfocal distance?
The distance from a lens’ optical center to the nearest point in acceptably sharp focus when the camera is focused on infinity.
What happens when you switch to a lens with a shorter focal length and smaller aperture?
The hyperfocal distance becomes shorter.
What is depth of field?
The range of distances in adequate focus on each side of the plane that’s focused upon.
What four factors control the depth of field for a lens?
- Focal length of lens
- Size of the circle of confusion
- Number used
- The distance from the lens to the object on which it is focused
On a 35mm camera system, where do you find the depth of field scale?
Usually on the lens barrel and sometimes on the camera body.
To what does the term “resolving power” refer?
The ability of a photographic lens or material to record or resolve fine detail.
Resolving power results from the combinations of what two factors?
The lens and image sensor used.
Why is photographic definition subjective?
It is an impression formed by the observer when viewing a photograph. The concept depends on the viewer and the situation involved.
What four factors determine the photographic definition of a print?
- Resolution
- Sharpness
- Pixelation
- Tonal reproduction
