Exposure Flashcards
What is the aperture in a camera?
The hole inside the camera lens that lets light in. Acts like an iris.
What is the shutter in a camera?
A device that allows light to pass for a determined amount of time to an exposed sensor to capture an image. It is constructed to automatically close after a certain time interval.
What is the definition of Exposure?
Exposure is the balance of lighting and settings in the camera.
What is an underexposed photo?
A photo that is too dark.
What is an overexposed photo?
A photo that is too bright.
What is the Exposure Triangle?
The Exposure Triangle is aperture, shutter speed and ISO.
What does a wide open aperture produce?
- Shallow depth of field - “bokeh”
- Brighter image
- Good for portraits
What does a smaller aperture produce?
- Focus throughout scene
- Darker image
- Good for landscapes
What does F/1 mean?
Large aperture, wide open
What does F/16 mean?
Smaller aperture, pinhole
What does the aperture control?
- Light
* Depth of field
What does a faster shutter speed produce?
- Freezing of action
- Darker image
- Good for sports, animals moving
What does a slower shutter speed produce?
- Blurring of action
- Brighter image
- Good for waterfalls, night photography
What does shutter speed control?
- Light
* Action and movement
What does 1/30 shutter speed mean?
- One thirtieth of a second
* Slower
What does 1/8000 shutter speed mean?
- One 8000 of a second
* Faster
What does increasing ISO produce?
- Increased exposure
* Brighter image
What does decreasing ISO produce?
- Decreased exposure
* Darker image
What does ISO control?
- Light
* Exposure
What does ISO 100 mean?
- Not light sensitive
* Best for outdoors
What does ISO 6400 mean?
- Very light sensitive
* Best for low light situations
What are metering modes?
The ways in which a camera determines exposure.
What is the Matrix/Evaluative metering mode?
- Standard setting
- Camera reads exposure from all areas of the frame
- Good for shooting events or diverse light situations
What is the Spot Metering mode?
• Camera reads exposure from a single focus point
What is Center-weighted metering mode?
- Camera reads exposure from the center of your frame and surrounding areas
- Best for portraits
What is exposure bracketing?
Taking multiple shots of the same image in order to find the optimum single shot for exposure.
What is HDR (High Dynamic Range)?
A post processing technique of layering photos of different exposures to create the perfectly exposed picture.
