Sunny 16
Calculate your base exposure without relying on any sensors. Master the classic Sunny 16 rule using intuitive visual weather scenarios.
What is the Sunny 16 Rule?
Before digital sensors, photographers had to read the environment. The classic Sunny 16 rule is a proven analog formula that still works perfectly on modern digital cameras:
- wb_sunny Bright Day: Start with an aperture of f/16.
- shutter_speed Shutter Speed: Set it to the inverse of your ISO (e.g., ISO 100 = 1/125s).
- calculate Sensorless: Digitizes that analog instinct to calculate base exposure anywhere.
Visual Scenarios
Light changes, and the math shifts with it. Estimate ambient light intuitively by selecting your current weather condition:
Shadow Adjustments
Shooting under a harsh sun but your subject is in the shade? Apply built-in shadow compensation to perfectly expose the darker areas of your scene without losing your baseline reading.
ND Filter Integration
Combine classic visual estimation with modern optical gear. Input your Neutral Density (ND) filter strength to instantly calculate the exact final exposure time needed.
