Thermal — Negative

An image editor that reads pictures like instruments read the world. Thermal maps luminance to an iron heat palette with a calibration sweep and scale bar; Duotone reduces everything to two inks around a breathing pivot; Contour steps the tones into poured topographic bands; Negative inverts the frame with a slow silver pulse and film-edge ticks. Drop in any image. Exports land social-ready as MP4, GIF, or PNG, rendered entirely in your browser. The free preview is fully interactive, watermarked, and capped at 540 px and 2 seconds.
