Photography Flashcards
What is a Drive dial?
Drive dial over on the left side of the camera controls what happens when you press down on the shutter release
What is aperture?
The aperture is the opening within the lens that limits the amount of light that can pass through it.
By changing the aperture value, you increase or decrease the size of that opening, thereby allowing more or less light into the camera.
Aperture is measured in f-stops, such as f/16 and f/14, but here’s the thing: The smaller the f-stop number, the larger the opening, and vice versa.
If you want less light to enter (small aperture), go for a larger f-stop. How large your lens’ aperture can open will depend on your lens. (Hint: A lens’ maximum aperture will be part of its model name, like a 50mm f/1.8 or a 24-120mm f/4.)
DOF
Depth of field. How much depth will be in focus within the image.
An image with a large DOF will have sharp focus from foreground to background, while a small, or shallow, DOF sees the focus concentrated on one particular plane, with foreground and background elements blurred away.
When thinking about the f-stop, choose a smaller number (larger aperture) to achieve a shallower DOF, or a larger number (smaller aperture) to increase DOF.
A small aperture(f-number) is used to keep both the
foreground and background in focus
How do you separate the subject from the background?
A shallow DOF (Depth of field)
When thinking about f-stop, choose a smaller number to achieve?
a shallower DOF
When thinking about f-stop, choose a larger number to
increase DOF
A larger aperture has a _1__ f-number and a small aperture has a __2__ f-number.
- small f-number
2. larger f-number
What is a shutter speed?
A camera’s shutter opens to allow light in.
Where does the shutter live?
Right in front of the imaging sensor and the shutter speed is the amount of time it stays open, like 1/60 second.
What does shutter speed control?
Shutter speed controls how motion is captured by the camera.
A fast shutter speed will
freeze moving objects in their track.
A slow shutter speed will
is used to take a steady picture without a tripod.
How do you achieve long-exposure photography
Slower shutter speeds lead to long-exposure photography. This is how you can blur things like waterfalls or create star trails in the night sky.
Slow shutter speed will add
motion blur to any moving elements in the frame, such as water and foliage, while stationary objects will remain sharp.
If you are using a very slow shutter speed, make sure your camera is
stabilized on a tripod or other surface to prevent camera shake.
