What is ISO in photography?

Back

ISO (International Standards Organization) measures the sensitivity of your camera's sensor to light. A higher ISO allows for shooting in lower light conditions but can introduce noise.

Front

What is the effect of high ISO settings on image quality?

Back

High ISO settings can lead to increased digital noise, which appears as graininess in the image.

Front

What is aperture in photography?

Back

Aperture refers to the opening in a lens through which light passes. It is measured in f-stops (e.g., f/2.8, f/16) and affects depth of field.

Front

How does shutter speed affect motion in photography?

Back

Shutter speed determines how long the camera's sensor is exposed to light. A fast shutter speed freezes motion, while a slow shutter speed can create motion blur.

Front

What is the Golden Ratio in photography?

Back

The Golden Ratio is a composition guideline that suggests dividing the frame into sections to create balance and harmony, often used in landscape photography.

Front

What is the relationship between ISO, aperture, and shutter speed?

Back

These three elements are known as the exposure triangle. Adjusting one affects the others, impacting the overall exposure and quality of the image.

Front

What is depth of field?

Back

Depth of field refers to the range of distance within a photo that appears sharp. A low f-stop (wide aperture) results in a shallow depth of field, while a high f-stop (narrow aperture) increases it.

Front

What is the purpose of using a low aperture (e.g., f/2.8) in photography?

Back

A low aperture allows more light to enter the camera, creating a brighter image and a shallow depth of field, which helps isolate the subject from the background.

Front

What is noise in digital photography?

Back

Noise refers to the grainy or speckled appearance in images, often caused by high ISO settings or long exposure times.

Front

What is the impact of lighting conditions on ISO settings?

Back

In low-light conditions, a higher ISO is often necessary to achieve proper exposure, but it can also increase noise.
