EXPOSURE TRIANGLE

 EXPOSURE TRIANGLE

is a foundational concept in photography that explains how three key settings work together to control the brightness (exposure) of an image



ISO in photography refers to your camera sensor’s sensitivity to light. It’s one of the three key settings in the exposure triangle, alongside aperture and shutter speed.


LOW ISO in photography refers to a setting where your camera sensor is less sensitive to light — typically values like ISO 100 or 200.

HIGH ISO in photography means your camera sensor is more sensitive to light, typically values like ISO 1600, 3200, 6400, or even higher.

SHUTTER SPEED:

in photography refers to the amount of time your camera’s shutter remains open to expose the sensor to light. It’s a critical part of the exposure triangle, along with aperture and ISO.


LOW SHUTTER SPEED 

speed refers to a slow shutter meaning the camera’s shutter stays open longer, allowing more light to hit the sensor. It’s typically anything slower than 1/60 of a second, like 1/30s, 1s, or even 30s.

HIGH SHUTTER SPEED 

means your camera’s shutter opens and closes very quickly  typically 1/500s, 1/1000s, or faster. It’s perfect for freezing motion and capturing crisp, detailed shots of fast-moving subjects.

UPERTURE: is the opening in a camera lens through which light passes to reach the sensor. It’s like the pupil of your eye  it can widen or narrow to control how much light enters.


LOW UPERTURE 

also called a wide aperture means the lens opening is large — typically f/1.2 to f/2.8. Despite the numbers being small, the opening is big.

HIGH UPERTURE 

Also called a narrow aperture means the lens opening is small typically f/11, f/16, or f/22. Even though the f-number is large, the actual opening is tight.
