1. What is the Exposure Calculator?

The Exposure Calculator helps photographers determine optimal exposure settings (shutter speed, aperture, and ISO) for various lighting conditions.

2. How Does the Calculator Work?

The calculator helps balance the three key elements of exposure:

Where:

• ISO — Camera sensor sensitivity
• Shutter Speed — Duration of exposure
• Aperture — Lens opening size

Explanation: The exposure triangle shows how these three elements work together to control the amount of light reaching the camera sensor.

3. Importance of Exposure Calculation

Details: Proper exposure is crucial for achieving desired photographic results, whether you want a bright, well-exposed image or creative underexposure/overexposure effects.

4. Using the Calculator

Tips: Enter your desired ISO, shutter speed, and aperture values. The calculator will help you find balanced exposure settings.

5. Frequently Asked Questions (FAQ)

Q1: What is the exposure triangle?
A: The relationship between ISO, shutter speed, and aperture that determines overall exposure.

Q2: What are standard shutter speed values?
A: Common values include 1/60, 1/125, 1/250, 1/500, etc., with each step doubling/halving exposure.

Q3: What are standard aperture values?
A: f/1.4, f/2, f/2.8, f/4, f/5.6, f/8, f/11, f/16, etc., with each full stop halving/doubling light.

Q4: How does ISO affect image quality?
A: Higher ISO increases sensor sensitivity but can introduce digital noise; lower ISO gives cleaner images but requires more light.

Q5: What is the "Sunny 16" rule?
A: A basic guideline: On a sunny day, set aperture to f/16 and shutter speed to 1/ISO for proper exposure.
