EV to Lux Calculator
The EV to lux calculator helps you convert exposure value (EV) into light intensity in lux quickly and accurately. Use this tool to understand lighting conditions for photography, cinematography, and lighting design.
Exposure Value to Lux
How to Use EV to Lux Calculator
Follow these simple steps:
- Enter the EV (Exposure Value): Input the exposure level of your scene.
- Choose the ISO setting: Commonly fixed at ISO 100 for these standard conversions.
- Click the “Calculate” button: Process the value instantly.
- View the result: Get the light intensity in lux immediately.
- Use EV at ISO 100 for standard calculations.
- Adjust ISO if your camera uses a different sensitivity.
- Higher EV values mean brighter lighting conditions.
How to Convert EV to Lux
You can convert EV to lux using this standard formula:
Step-by-Step Example
Let’s convert EV 10 to lux:
1. Identify the EV value: EV = 10
2. Apply the formula: Lux = 2.5 × 210
3. Calculate 210: 210 = 1024
4. Multiply: Lux = 2.5 × 1024 = 2560 Lux
Final Answer: EV 10 ≈ 2560 lux
- Low EV (0–5): Very dim light
- Medium EV (6–10): Indoor lighting
- High EV (11–15): Bright daylight

FAQs About EV to Lux Calculator
EV (Exposure Value) measures the amount of light in a scene. It combines shutter speed and aperture into a single value.
Lux measures light intensity. It shows how much light falls on a surface.
Yes. Use the formula: Lux = 2.5 × 2^EV
EV values often assume ISO 100. Changing ISO affects brightness and final lux values.
It is used in photography, cinematography, lighting design, and architecture to ensure proper illumination levels.
