Calibration Flow runs on a clear model: free registration + an à la carte Pro subscription. No guest mode, no time-limited demo — a (free) account gives access to the whole calibration workflow with no paywall on the core functions. The Pro subscription at €9.90/month unlocks the extended quotas and the advanced functions. When you buy a Luminograph from Vision Picturale, 1 year of Pro is included.
This page documents the two access tiers and the Luminograph bonus.
