ND Filter Calc vs NDReady

A simple neutral density filter calculator for photographers. Has a count-down timer for shutter speeds of 3 seconds and above.

Stop guessing your settings. NDReady reads a single photo and tells you exactly which ND filter and camera settings you need to nail the shot — in any light. Built for action sports videographers who shoot fast and can't afford to fumble with exposure on the trail, in the surf, or mid-flight. HOW IT WORKS Snap or import one photo. NDReady analyzes the light and hands you the right ND filter strength and exposure settings instantly. No light meter, no trial and error, no missed footage. CONDITIONS ENGINE Go beyond a basic calculator. The Conditions Engine cross-references your spot's history, live light data — cloud cover, sun elevation, and how open your location is — to predict the settings you'll actually need before you even get there. LOOK MATCHER Build a watchlist of the cinematic looks you're chasing. NDReady matches current conditions to the footage you want and tells you how to get there. SPOT HISTORY Every location you shoot gets smarter over time. NDReady remembers your spots and learns what works.
