Chapter 6 Flashcards
Describe the basic forms of film:
Film Cassettes- used in 35mm cameras and contains a supply spool.
Cartridge Film- contains the supply and take-up spools. No longer used.
Sheet Film- used in view cameras
Roll Film- Used in TLR cameras. Medium Format film
A good photographer must be part TECHNICIAN and part ARTIST.
•Artist: oIdentify good scenes oFrame the image oCreate meaning/ meaningful images •Technician: oOperate the camera oDevelop film oPrint pictures
Film must be loaded in to the camera so that the _______ faces the lens.
Emulsion
- If the camera is not well supported when a photo is taken, the picture will be ________
Blurred
A tripod should be used when…
- There is not enough light for at least a 1/60 second shutter speed.
- Using a view camera.
- Making close-up photos.
A quick jab on the shutter release usually results in a ______picture. The shutter release should be depressed in a _________, _______ manner.
Blurry; smooth; even
A sharp photo requires….
Focusing
Range finder cameras use a….
Superimposed focusing system
Two basic types of focusing screens are used on SLR cameras:
A. SPLIT-IMAGE SPOT. A circular spot in the center of the focusing screen breaks the image into two parts that do not match up. The lens is properly focused when the two images form a single image.
B. MICROPRISM. A small circle in the center of the focusing screen appears dark and the image within the spot is blurred until the lens is properly focused.
What does depth of field mean?
The range of depth that is in focus.
Focusing zone cameras
Cameras with fixed focal distances.
•The subjects must be specific distance from the camera in order to be in focus.
•This was primarily on cheap “toy” cameras.
Light Meters
- Measures the volume of light that will hit the film.
2. It makes setting the shutter speed and aperture correctly possible.
Why is a Through-The-Lens (TTL) metering system preferred over a hand held exposure meter?
It compensates for different lenses and filters as the light passes through them.
How are exposure meters calibrated?
18% grey is the middle value on the value scale
- The technique of taking a picture several times with different aperture/shutter speed combinations to assure proper exposure is called __________
Bracketing
Averaging Meter System
two or more sensors that measure the average amount of reflected light in the image
Backlighted Subject
a silhouetted subject as result of a light source being placed behind the subject
Bracketing
taking a picture several times with different aperture/shutter speed combinations to assure proper exposure
Center-weighted Metering System
multiple sensors that averages the amount of reflected light, but place extra emphasis on the center of the scene
Focusing Zone
lens settings based on fixed ranges that are in focus. This is only found on cheap cameras.
Follow Pointer Lens
two needles used to indicate the metered exposure. One needle indicates the recommended exposure and the second needle indicates the current exposure settings.
Framing
partially or completely surrounding the subject with objects in the foreground
Incident Light Exposure System
an instrument that measures the light falling on the subject
LED Display
LED lights or images used to replicate the Single Pointer and Follow Pointer Displays
Meter Calibration
adjusting the light sensors to produce medium grey tones when 18% of the light is reflected off the subject.
Metering
measuring the amount of light reaching the film
Panning
following a moving subject with the camera while taking the picture to keep the subject in focus
Red Eye
the result of the flash being too close to the eyes resulting in reflection of the blood vessels
Reflected Light Exposure Meter
light exposure meter- a device that measures the light bouncing off a subject
Single Needle Display
a single needle that moves between fixed points to indicate the metered exposure
Spot Metering
a single sensor measuring the reflected light at the center of a scene. Extra care must be used to measure the subject.
TTL Metering
(Through the Lens) built in light sensors that measure the light traveling through the lens of the camera.
