Exposure Value Calculator
Calculate the exposure value (EV) from camera settings
About this calculator
An Exposure Value Calculator determines the EV number based on your camera's aperture and shutter speed settings. EV is a standardized way to express exposure combinations, making it easier to compare different camera settings and maintain consistent exposure across various lighting conditions. This tool is essential for photographers who want to understand exposure relationships, work with light meters, or achieve precise exposure control in manual mode.
How to use
Enter your camera's aperture setting (f-stop) and shutter speed into the calculator. The tool will instantly compute the corresponding Exposure Value number. Use this EV number to compare different exposure combinations or reference lighting conditions for consistent photography results.
Frequently asked questions
What is Exposure Value (EV)?
EV is a number that represents the combination of aperture and shutter speed settings, standardizing exposure measurements across different camera configurations.
Why are EV calculations important?
EV calculations help photographers maintain consistent exposure, work with light meters, and understand equivalent exposure combinations for creative control.
How do aperture and shutter speed affect EV?
Wider apertures (lower f-numbers) and faster shutter speeds increase EV values, while smaller apertures and slower speeds decrease EV values.
