• Pure Exposure Value: EV₁₀₀ = 4.97 (based on shutter & aperture)
• Luminance: 4 cd/m² = 0.37 cd/ft²
• Luminance: 1.17 fL (foot Lambert)

Explanation

• Explanation: EV is an estimation of how much light you need for a decent photo with these settings.
• This can be natural light (sun, moon), artificial continuous light (lamps) or strobes.
• If your camera settings indicate EV10 and you actually have EV=15 in your scene, your photo will be overexposed. If your settings need EV=10 and you actually have EV=3 your photo will be underexposed.

Examples

• Definition: 1s at f/1.0: EV0
• Sunny 16 Rule : EV15
• Shooting film in broad daylight : EV12
• Extreme ISO in dark places (bars at night) : EV0
• Long exposure in broad daylight: EV12
