Intro Study Guide (test Tuesday) Flashcards
Exposure
The amount of light you let into your camera
What kind of shutter speed would you need to freeze motion (i.e leaves falling)?
A high shutter speed
Lowest SS for handheld photo
1/125
1/60-1/4000
Camera shutter speed
Base ISO
100
Not enough ISO?
100->200->400->800
What are the three parts of the exposure triangle?
Aperture, Shutter Speed, and ISO
Shutter speed (SS)
Length of time your camera takes a picture or the shutter is open
Motion-blur SS
1/80, 1/100
Lowest hand-held photo SS
1/125
Portrait SS
1/125, 1/160, 1/200, 1/250
What is a good SS range for shooting portraits outside?
1/125-1/320
If you want to stop time or freeze motion, do you use a higher or lower shutter speed?
You set a high shutter speed
If you want to show motion blur, do you set a higher or lower shutter speed?
You set a low shutter speed
If you want to shoot a fast moving sport like volleyball, basketball, or football, what would be a good shutter speed range, depending on lighting?
1/1000-1/1600
1/1000, 1/1300, 1/1600
Fast-moving sports/frozen in time
If you want to show blur in a waterfall, what would be a good shutter speed?
Up to 12 seconds
The lower the shutter speed, the more ______ blur is shown in the photo
The lower the shutter speed, the more -motion blur- is shown in the photo
The higher the shutter speed, the more you ______ time and the image.
The higher the shutter speed, the more you stop time and the image
Aperture
The amount of light let into the camera through the iris. (size of opening lens/iris). The larger the opening, the more light-therefore the more exposure.
The wider the aperture, the more _____ you let in the camera.
The wider the aperture, the more light you let in the camera
Why does a smaller aperture have a larger number?
It is measured in fractions
The nine common f-stops
3, 4, 4.5, 5, 5.6, 6.3, 7.1, 8, 9, 10, 11, 13, 14, 16, 18, 20, 22
What aperture is larger? f/2 or f/11?
f/2
What is depth of field?
The amount of your photo/scene from front to back that´s in focus.
A wider aperture will give you a _______ depth of field, so that images in the background will appear blurry. This will make your subject pop and draw the eye.
A wider aperture will give you a _______ depth of field, so that images in the background will appear blurry. This will make your subject pop and draw the eye.
Aperture controls depth of field (true or false?)
True
A small aperture will give you a _____ or wider depth of field where everything appears to be sharp. What kind of photos are these good for?
A small aperture will give you a larger or wider depth of field where everything appears to be sharp. This is good for landscape photos.
ISO
The setting that brightens/darkens a photo
You can raise the ISO to _____ your photos in situations where lighting is too dim.
brighten
But the more you raise the ISO number, the more ____ or ¨noise¨ you´ll have in the photo.
But the more you raise the ISO number, the more grain or ¨noise¨ you´ll have in the photo.
The base ISO on our cameras is ______, which is a good place to start for shooting outdoors or in well lit situations. You can raise it to ___, 400, or even 800 if you don´t have enough light.
The base ISO on our cameras is 100 ISO, which is a good place to start for shooting outdoors or in well lit situations. You can raise it to 200, 400, or even 800 if you don´t have enough light.
What does the exposure triangle indicate?
That if you change one component (aperture, ISO, SS), then you need to compensate. They all affect each other. One changes=all change the photo.
How can you get a blurred water affect in the waterfall?
Very slow shutter speed - about 12-20 seconds (up to 12secs)
