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.

EFFECTS-BASED ND FILTER CALCULATOR

Instead of starting with the filter you have, start with the effect you want. Xposure lets you choose your desired creative outcome—like smoothing water or creating dreamy skies—and calculates the exact ND filter strength you need.

• Select from visual effect categories: Water Effects, Cloud Movement, Daytime Architecture, and more
• Automatic calculation of recommended ND filters based on your base shutter speed
• Filter stacking options for photographers with multiple ND filters
• Fine-tuned for accuracy, even in changing lighting conditions
• Instantly transfer your results to the ND Calculator with one tap—automatically set up your filter configuration and start timing

TRADITIONAL ND CALCULATOR

Already know your ND filter strength? Use the classic mode:

• Enter your base shutter speed and filter strength (e.g., ND8, ND64, ND1000)
• Get your adjusted exposure time instantly
• Supports filters from 1 stop to 20 stops
