Which three controls make up the exposure triangle?

Aperture, shutter speed and ISO

What does a wide aperture (small f-number such as f/2.8) do to depth of field?

It gives a shallow depth of field, blurring the background

It introduces noise, a grainy texture that reduces image quality

The aperture, while the camera chooses the shutter speed

A small or undiffused source, giving sharp, high-contrast shadows

The colour temperature of the light source

Highlights are blown out to featureless white

Placing key elements on the lines or intersections of a three-by-three grid

They draw the viewer's eye along them, usually towards the subject

Following a moving subject with the camera at a slow shutter so it stays sharp while the background streaks

Capture, post-production editing, presentation

Because editing cannot create what was not captured well; an underexposed file gains noise when brightened and a soft image cannot be sharpened
