Value Caliper, a pocket value-finder for painters

Why it surfaced

Value Caliper turns a painter’s familiar problem into a precise interaction: tap the shadow side and sunlit side of a tree, compare them on a 0–10 scale, then adjust point or region sampling, step placement, and mounting-board contrast. It also says photos are processed in the browser and never uploaded.

A browser-based painting-analysis tool that measures the value gap between two points in a photo and reduces the image to a chosen number of value bands.
