Basics For Speedlight Flashcards
Which mode do you use in function of distance subject to speed Light?
- when distance between subject and Speedlight changes, use E-TTL Mode,
- when distance remains fix, use Manual Mode.
Two types of lights
- Ambient light
2. Created light (flash, etc.)
How do increase or decrease the amount of light in your shot?
Use Flash Exposure Compensation (FEC) to increase or decrease the amount of light in your shot.
What type of light do aperture and shutter speed control?
- Aperture controls created light (flash) exposure.
- Shutter speed controls ambient light exposure.
What is dynamic range?
Dynamic range is the maximum range of bright and dark a camera’s sensor can capture/record.
What is a stop?
A stop is a doubling or halving of any exposure component–ISO, shutter speed or aperture.
What is the range, from wider to borrower, of whole f/stops?
f/1, 1.4, 2, 2.8, 4, 5.6, 8, 11, 16, 22, 32, 45, 64, 128.
What is stopping down?
It is a change in aperture to a smaller f/stop, from f/5.6 to f/8 for instance.
What is opening up?
A change in aperture to a larger f/stop, from f/16 to f/11 for instance.
What is affecting the depth of field?
- Aperture f/1.4 has a shallow Depth of Field while f/22 has a deep DOF.
- Focal length: wide angle have a deep DOF while long lenses have a wide range of DOF.
- Focussing distance: long focal length tend to flatten out the background, known as compression
What is the relation of Aperture to Shutter Speed?
If the Aperture is small, the Shutter Speed is slow.
If the Aperture is wide, the Shutter Speed is fast.
What is Exposure Value or EV?
EV refers to all the equivalent exposures (combinations of shutter speed and aperture) for a given amount of light (see Fig. 2.13).
What is Spot Metering?
Spot metering is the basis of how to use Flash Exposure Lock (FEL).
How do you increase or decrease Metered Exposure?
Use Exposure Compensation (EC) to increase or decrease the camera’s metered exposure.
