Important Triangle Flashcards
What is the aperture in a camera?
The aperture is an opening inside the lens that controls how much light passes through to the camera’s sensor.
How is aperture measured?
It’s measured in ‘f-stops’ (like f/1.4, f/2.8, f/8, etc.).
What does a smaller f-number indicate about the aperture?
A smaller f-number (like f/1.4) means a wider opening, letting in more light.
What does a larger f-number indicate about the aperture?
A larger f-number (like f/16) means a smaller opening, letting in less light.
What effect does aperture have on exposure?
It affects how bright or dark your photo is.
What is depth of field?
Depth of field is the area of your photo that’s in focus.
How does a wide aperture affect depth of field?
A wide aperture (small f-number) creates a shallow depth of field, blurring the background.
How does a narrow aperture affect depth of field?
A narrow aperture (large f-number) creates a deep depth of field, keeping more of the scene in focus.
What is shutter speed?
Shutter speed is how long the camera’s shutter stays open, allowing light to reach the sensor.
How is shutter speed measured?
It’s measured in seconds or fractions of a second (like 1/1000s, 1/60s, 1s).
What effect does a fast shutter speed have on motion?
A fast shutter speed (like 1/1000s) freezes motion.
What effect does a slow shutter speed have on motion?
A slow shutter speed (like 1s) creates motion blur.
What does shutter speed affect besides motion?
It also affects exposure: how bright or dark your photo is.
What is ISO in photography?
ISO is your camera’s sensitivity to light.
What does a lower ISO value indicate?
A lower ISO (like 100) means less sensitivity to light.
What does a higher ISO value indicate?
A higher ISO (like 3200) means more sensitivity to light.
What effect does increasing ISO have in low light?
In low light, increasing the ISO brightens your photo.
What is a potential downside of using a higher ISO?
A higher ISO can introduce ‘noise’ (graininess) into your image.
What does ISO affect in a photo?
It affects exposure and image noise: the amount of grain in your photo.
What is the Exposure Triangle?
The Exposure Triangle consists of aperture, shutter speed, and ISO, which work together to control the exposure of your photos.
What happens when you change one setting in the Exposure Triangle?
Changing one setting often requires adjusting the others to maintain the desired exposure.
