Shutter Speed Calculator
Calculate optimal shutter speed for any lighting condition, aperture, and ISO setting
Calculate Shutter Speed
Select the lighting condition that matches your shooting environment
Lower f-numbers = wider aperture, more light
Higher ISO = more sensitive to light, more noise
Recommended Shutter Speed
Camera Settings: f/8, ISO 100, EV 15
Photography Tip: Very fast shutter - Perfect for high-speed action, sports, wildlife, and freezing rapid motion completely.
Exposure Analysis
Example Calculation
Milky Way Photography
Scenario: Night photography under clear starry sky
Lighting Condition: EV -7 (Deep star field/Milky Way)
Camera Settings: f/2.8, ISO 6400
Formula: Shutter Speed = (100 × 2.8²) ÷ (6400 × 2⁻⁷)
Calculation: (100 × 7.84) ÷ (6400 × 0.0078125) = 784 ÷ 50 = 15.68 seconds
Sports Photography
Scenario: Bright daylight sports action
Settings: EV 15, f/5.6, ISO 400
Result: 1/1000 second - Perfect for freezing motion

Understanding Shutter Speed Calculations
What is Shutter Speed?
Shutter speed is the length of time the camera's shutter remains open to expose the sensor to light. It's measured in seconds or fractions of a second (like 1/500s). Faster speeds freeze motion, while slower speeds create motion blur and allow more light.
The Formula
Shutter Speed = (100 × aperture²) ÷ (ISO × 2^EV)
- aperture: f-number (like 2.8 for f/2.8)
- ISO: Sensor sensitivity (100, 200, 400, etc.)
- EV: Exposure value for lighting condition
Creative Applications
- •Fast (1/1000s+): Freeze sports action, wildlife movement
- •Medium (1/60-1/250s): General photography, portraits
- •Slow (1/30-1s): Flowing water, motion blur effects
- •Long (30s+): Star trails, light painting, astrophotography
Practical Tips
- •Use tripod for shutter speeds slower than 1/60s
- •Consider image stabilization capabilities
- •Balance ISO to minimize noise
