Intro to Photography Flashcards
What are Point and Shoot Cameras usually referred as
consumer
What are three features of a Prosumer Digital Camera
used to describe advanced models of P&S (entry DSLR’s)
Extended zoom range
more advanced manual features
Digital SLR features
Single Lens Reflux
larger sensors better quality
what does SLR mean
Single Lens Reflux
Nikon Movement Compensation
Vibration Reduction
Canon Movement Compensation (IS)
Image Stablization
Pentax Movement Compensation (SR)
Shake Reduction
Sony Movement Compensation (SSS)
Super Steady Shot
What is the difference between a digital SLR an a point and shoot camera?
Image Quality
What is each digital image made from?
millions of tiny squares (pixels)
Are all sensors equal?
No larger sensors contain larger pixels which produce better quality
When does a correct or good exposure occur?
When you contain as much detail as possible in both dark and light parts
Dynamic Range is?
how much range in which you can capture detail from light to dark
Highlight - bright
Shadows- dark
What are the three factors which influence the exposure of an image
Shutter Speed
Aperture
ISO
Shutter Speed it?
How long the shutter is open exposing the image sensor to light ( how long the camera sees the picture)
What is shutter speed measure in? And what are the ranges?
Seconds
30 down to 1/8000
Fast shutter speeds are used for
600 and up, used to stop motion and will freeze the subject.
Slow motion speed can be used to
portray movement or speed (1/60 or slower)
Very slow shutter speeds can be used in a very low light situation to obtain?
correct exposure or achieve dramatic affects (5 sec or slower)
As you shutter speed decrease what will happen
you are most likely to get a blurry picture having to hold the camera steady longer
Aperture is
hole or opening through which light is admitted.
Where is the aperture
inside the camera lens; system of blues which open and close to increase or decrease the opening through which light passes into the camera
what are the aperture values expressed as
in numbers called f/stops
A small number represents more light coming into the camera. Example?
f/1.4 lets more light in than f/22
What does aperture also control
DOF Depth of Field
what is the DOF
Depth of Field how much your image is in focus
What will a wide aperture give regarding the DOF
shallow DOF can be used to isolate a subject
ISO refers to what
light sensitivity of the sensor
HIGH ISO means what
more sensitive to light meaning making less light to get the right exposure
The Rule of Thirds
placing your subject or elements along any of these liens and especially on or near the intersecting points makes a photo attractive
Rule of Thirds for portraits
eyes positioned near one of the horizontal lines to give more power and naturally to the photo
Rule of thirds for landscape
horizon is aligned to any of the horizontal lines
What are CMYK
cyan, magenta, yellow an black
What does CMYK produce
produces color prints
what does it mean to say CMYK colors are subtractive
the colors get darker as you blend them together. The color grows brighter and increases the intensity.
What does the K in CMYK stand for
key because the four color printing g colors are aligns with the black key plate.
