1. What is a Shutter Time Calculator?

Definition: This calculator determines the shutter time (exposure time) based on shutter speed frequency.

Purpose: It helps photographers and videographers calculate the exact exposure time for their camera settings.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( t \) — Shutter time (seconds)
• \( f \) — Shutter speed (Hertz, Hz)

Explanation: The shutter time is simply the reciprocal of the shutter speed frequency.

3. Importance of Shutter Time Calculation

Details: Proper shutter time calculation ensures correct exposure, prevents motion blur, and helps achieve desired photographic effects.

4. Using the Calculator

Tips: Enter the shutter speed in Hertz (Hz). Common values range from 1/30 (0.033Hz) to 1/8000 (0.000125Hz) for photography.

5. Frequently Asked Questions (FAQ)

Q1: What's the relationship between shutter time and shutter speed?
A: Shutter time is the exposure duration, while shutter speed is how frequently the shutter opens (frequency). They are inversely related.

Q2: What are typical shutter speed values?
A: Common values range from 30Hz (1/30s) for low light to 8000Hz (1/8000s) for fast action photography.

Q3: How does shutter time affect my photos?
A: Longer times allow more light but may cause blur, while shorter times freeze motion but require more light.

Q4: What's the difference between mechanical and electronic shutter?
A: Mechanical shutters have physical limitations, while electronic shutters can achieve much faster speeds.

Q5: How do I convert shutter time to fractions?
A: The calculator shows decimal seconds. For fractions, use the reciprocal (e.g., 0.004s = 1/250).
