Module 2G - Speedlights Flashcards

Flashcards for reviewing key concepts about speedlights in photography.

Speedlight Power Output

Varies from brand to brand and with different models, determining the f-stop ranges for exposures with the flash.

Manual Mode with a Speedlight

Mode where the flash delivers a consistent measurement of light regardless of ambient exposure, crop, or lens focal length.

TTL Mode

Mode where light passes through the lens and is measured at the sensor, with the camera and speedlight working together to determine flash output.

Flash Bracket

Raising the flash higher above the camera to reduce the red eye effect and prevent shadows behind the subject.

Disabling Zoom Head Tracking

Setting the zoom to Manual Zoom to disable zoom head tracking, providing a consistent and reliable output every time the flash fires.

Inverse Square Law

States that moving the light closer increases the exposure and moving the light further away decreases the exposure.

Using Speedlight On-Camera

Results in harsh and flat lighting due to the small light source and direct frontal illumination.

Tracking controls

Controls that alter the output of the flash based on the focal length of the lens in use.

Zoom head

The zoom head moves in and out to focus the light or spread the light to coincide with the angle of view of the lens.

TTL or eTTL

Using a zoom lens, and photographing at various camera-to-subject distances.
