Xposure – ND Calculator for Long Exposure Photography

Master long exposure photography with the ultimate ND filter calculator app.

Xposure is designed for photographers who love creative control and stunning results. Whether you’re shooting silky waterfalls, smooth cloud streaks, or ghost-free architecture, Xposure takes the guesswork out of ND filter use.

Xposure offers two powerful tools to plan your perfect exposure, every time.
