About Exposure Calc
Exposure Calc is a free, browser-based utility designed to make image editing as quick and frictionless as possible. The goal was to keep the path from "open the page" to "get the result" as short as possible. No mandatory account, no cookie wall, no upsell at every step. It is one of about a hundred image tools that share the same philosophy: do one thing, do it well, get out of your way.
