Fast and Accurate Shutter Speed Calculation for ND Filters

This app is a simple calculation tool designed to instantly determine the correct shutter speed when shooting photography with ND filters.

By selecting a normal shutter speed and the ND filter strength, the app automatically calculates the required shutter speed with the filter attached. No more complex calculations when shooting long exposures or daytime slow shutter photography.

The app also allows you to calculate the original normal shutter speed from a shutter speed taken with an ND filter. This is useful for reviewing shooting conditions or planning settings for reshoots.

Key Features:
- Automatically calculates shutter speeds when using ND filters
- Reverse calculation from ND-adjusted shutter speed to normal speed
- Intuitive and distraction-free user interface
- Ideal for landscapes, waterscapes, and long exposure photography
