Art 145 Photography Concepts Review

These flashcards cover key vocabulary and concepts from the Art 145 lecture notes on photography basics, exposure, and digital editing.

Exposure

A measure determined by Intensity x Time x ISO.

Reflective light

Measured by 18% gray card, indicating the amount of light reflected off the subject.

Intensity

The amount of light recorded on the sensor, controlled by the size of the lens opening.

Shutter speed

The actual length of time light enters the camera.

S or TV shutter priority

Photographer controls shutter speed, camera controls aperture.

A/AV Aperture priority

Photographer controls aperture, camera controls shutter speed.

Manual mode

Photographer controls both shutter speed and aperture.

ISO

The sensor’s sensitivity to light, with full stop values of 100, 200, 400, and 800.

Full f/stops

F/stops including f/2, f/2.8, f/4, f/5.6, f/8, f/11, f/16, f/22.

Bulb mode (B)

Allows the shutter to remain open as long as the shutter button is pressed.

Halving vs. Doubling light

f/2.8 allows double the amount of light as f/4.

Depth of field

Distance between the sensor, foreground, middle ground, and background; how much is in focus.

Histogram

Displays image tonality, grayscale, and highlights and shadows.

Digital workflow

A sequential method of working to stay organized in digital editing.

Raw vs JPEG

Raw is an unprocessed image (more information) whereas JPEG is processed and compressed.

Print quality

300 ppi minimum for prints vs 72 ppi for web use only.

Lightroom

Software module used for importing, exporting, organizing, and rating images.

Metadata

Embedded information within the image containing technical data.

Equivalent exposures

Different settings yielding the same exposure, for example, 1/125 @ F/11 is the same as 1/250 @ f/8.

Selective depth of field

Achieved with apertures of 2.8, 4, and close to the subject.

Maximum depth of field

Achieved using apertures of f/11, f/16, f/22.
