Neutral Density Calculator is a practical photography utility that quickly converts your base exposure to the correct shutter speed when using ND filters. Designed for photographers and videographers, it streamlines long exposure planning, filter stacking, and on-location shooting.
Core features:
- Fast exposure conversion: input your base shutter speed, ISO, and aperture, then select ND strength in stops or optical density to get the corrected shutter speed.
- Filter stacking: combine multiple filters and see the total light reduction instantly.
- Long exposure aid: built-in timing tools help you execute multi‑second or bulb exposures with confidence.
Why it stands out: simple, accurate, and purpose-built for long exposure photography, ND filter use, landscape shoots, and video setups following common shutter rules. Keywords: ND filter calculator, long exposure, exposure calculator, shutter speed calculator, photo and video utilities.

How to use:
1. Download and open the app, then set your preferred units for ND strength (stops or optical density) and default camera settings if available.
2. Meter your scene without any filter and enter the base exposure: shutter speed, ISO, and aperture.
3. Select the ND filter strength or add multiple filters to stack their effect; the app will display the corrected shutter speed.
4. If the result exceeds one second or requires bulb mode, start the built‑in timer to guide the exposure from start to finish.
5. Save frequently used filter combinations or settings as presets for faster setup on future shoots and adjust as lighting changes on location.
