ND Exposure Calculator
Paran
ND Exposure Calculator is a calm local exposure board for photographers who need a fast answer before setting up a shot. Enter a meter reading, choose the aperture and ISO you want to shoot, add ND filter stops, and ND Exposure Calculator calculates the matching shutter time. Use quick starts for water, street motion, cloud drift, and night trails, then share the final recipe as clean text. Use it for: - Converting a metered exposure into a long exposure plan - Checking ND filter shutter times without a bulky camera app - Comparing aperture, ISO, and shutter changes in one place - Preparing tripod shots, water blur, cloud movement, and night trails - Sharing a compact exposure recipe with your note ND Exposure Calculator is intentionally not a camera app, astronomy planner, cloud editor, or subscription toolkit. It is a paid app with no subscriptions, no ads, no in-app purchases, no account, no tracking, no location permission, no camera capture, no photo library access, and no server upload.
