- Added brightness-smoothing parameter (0-1, default 0.1)
- Implements exponential moving average to filter transient brightness changes
- Samples brightness every frame but smooths before adjusting exposure
- Reduces oscillation from people/cars/birds moving through scene
- Updated DEBUG.md with complete implementation details
Recommended settings for dawn/dusk time-lapse:
ramp-rate=vslow update-interval=1000 brightness-smoothing=0.1
