Sunny 16 Trainer Mode
Training game that asks you to predict exposure before checking the meter.
Where to find it
Tools tab Sunny 16 Validation (validation only for now)
Summary
Training mode that quizzes you on Sunny 16 rule predictions. Currently the validation half is shipping; the guess-and-score loop is the planned other half.
How it works
What is shipping today
The validation step works: tap on a sunlit scene and the app tells you whether your meter agrees with the Sunny 16 prediction. That is the same flow used for sensor calibration.
What is still planned
The trainer half: before each measurement, the app asks you to guess the correct aperture/shutter pair for the scene you are about to meter. After you take the measurement it scores your guess and tracks your accuracy over time so you can build calibration intuition without picking up a separate light meter.
Why it matters
Exposure intuition is the gap between knowing the Sunny 16 rule on paper and being able to look at a scene and call the exposure within a stop. The trainer gives you a feedback loop on real scenes you are already metering.
