Photography and Studio Lighting Lecture Notes

Vocabulary flashcards covering photography gear, camera controls, lens focal lengths, studio flash modifiers, and image composition based on the lecture notes.

Fresnel Lamp

A studio light equipped with a Fresnel lens that focuses light into a tight, controllable beam.

Ring Light

A continuous light source that replaces reflector lamps, characterized as lightweight, portable, and battery-powered for up to $8\,h$.

ISO Sensitivity

The measure of a film or digital sensor's sensitivity to light, where lower values like $100$ or $200$ are used for bright daylight and higher values like $1600$ or $3200$ are used for night conditions.

Photosensitive Sensor

The digital equivalent of a film negative in a camera body that captures incoming light to generate an image.

Lens

An optical assembly of individual glass lenses that directs light into the camera body onto the sensor and determines the field of view.

Aperture

An adjustable diaphragm inside the camera lens that controls the amount of light reaching the sensor and determines the depth of field.

Shutter Speed

The length of time the camera shutter remains open to expose the sensor to light, affecting exposure and motion blur.

Focal Length

The optical property of a lens defining its angle of view, ranging from wide angles ($8\,mm$ to $35\,mm$) to narrow telephoto angles ($85\,mm$ to $300\,mm$).

Fisheye Lens

An ultra wide-angle lens with an extreme focal length of around $8\,mm$ offering a panoramic field of view up to $180^\circ$.

DSLR Camera

A camera system that uses an internal reflex mirror mechanism to provide an optical preview of the scene through the lens.

Mirrorless Camera

A camera system that omits the internal mirror mechanism, displaying the live view image digitally from the sensor.

Rule of Thirds

A compositional rule where an image is divided into a grid, positioning key elements at the line intersections to draw viewer attention.

American Shot

A framing style in portrait photography that captures the subject from the knees upward.

Bowens Mount

A standardized attachment socket on the front panel of studio flash units used to attach light modifiers.

Photocell

A light sensor on the rear panel of a flash unit that detects the flash of another lamp to trigger a synchronized flash.

Radio Trigger

A wireless trigger system that uses radio waves to fire studio flash units remotely without requiring a line of sight.

Infrared Trigger

An optical flash trigger mechanism that operates via line-of-sight infrared light signals between the transmitter and the lamp.

Octabox

An eight-sided softbox modifier with a diameter of $150\,cm$ and white diffusion fabric used to produce soft, scattered light for portrait and beauty photography.

Stripbox

A long, narrow softbox light modifier used to produce directional rim and contour lighting on a subject.

Beauty Dish

A parabolic metallic light modifier with a central deflector plate that scatters light outward for beauty portraiture.

Tripod Load Capacity

The maximum equipment weight specified on the product box or by the manufacturer that a tripod setup can safely support.

Ilford

A brand of analog film where numbers printed on the film negative indicate its ISO sensitivity rating.

Kodak Ektar H35

A half-frame analog camera model referenced in the photography lecture notes.

Terry Richardson

A prominent fashion photographer referenced in the digital photography lecture notes.
