ND Exposure Calculator Support

Getting Started

Open ND Exposure Calculator, enter your base meter reading, choose the aperture and ISO you want to shoot, then add ND filter stops. The app calculates the matching shutter time and shows whether a bulb timer is useful.

Privacy

ND Exposure Calculator works locally. It has no account, tracking, ads, subscriptions, camera capture, photo library access, or server upload.
