Photography Fundamentals Quiz

Aperture numbers are inversely related - f/16 is a smaller opening than f/4. A smaller aperture (higher f-number like f/16) produces greater depth of field, meaning more of the image from foreground to background appears sharp. This is a fundamental principle in photography.

A fisheye lens is an extreme wide-angle lens that captures a very wide field of view (often 180 degrees or more) with significant barrel distortion, creating a curved, hemispherical appearance. They are not limited to underwater photography and are rarely used for portraits due to their extreme distortion.

On a sunny day with ISO 100 film, the 'Sunny 16' rule suggests f/16 with shutter speed 1/ISO (1/100 or 1/125). The closest standard shutter speed is 1/125. This rule is a foundational exposure guideline for daylight photography.

Photographic filters are placed in front of the lens to modify the light entering the camera - they can change colors, reduce reflections, darken skies, or create special effects. They don't physically clean anything or deal with used photons.

Depth of field refers to the zone of acceptable sharpness in front of and behind the point of focus. A deep depth of field (f/16) keeps everything sharp, while shallow depth of field (f/2.8) keeps only the subject sharp with blurred background.

In black and white photography, filters lighten their own color and darken complementary colors. A red filter allows red light to pass through freely, so red objects appear lighter in the final print. Green and blue objects appear darker because those colors are absorbed.

ISO 100 film is slower and less sensitive to light than ISO 400, so it requires more exposure (more light) to produce a properly exposed image. Lower ISO films produce finer grain, while higher ISO films are more sensitive but produce more grain.

Over-exposure means too much light reaches the film or sensor, causing the image to appear lighter than normal. A slide that is over-exposed will be washed out and lack detail in bright areas.

A zoom lens is designed with variable focal length, allowing you to change the magnification without changing lenses. This is the defining feature that distinguishes zoom lenses from prime (fixed focal length) lenses.

In photography, a 'fast' lens refers to one with a larger maximum aperture (smaller f-number like f/1.4 or f/2.8). Larger apertures allow more light to reach the sensor, enabling faster shutter speeds in low-light conditions.
