ARK Infrared
Read full descriptionHide full description
ARK Infrared turns ordinary photos into infrared photographs โ the way they would look shot on IR film through a real filter. It is not a color preset. The engine reads every pixel for the physical evidence infrared responds to โ chlorophyll, sky light, tungsten heat โ and rebuilds the image the way film would record it. Foliage glows. Skies go black. Nothing is painted on. FOUR FILMS BW โ black & white infrared, 590โ850 nm. The look of Kodak HIE: glowing foliage, dark skies, halation bleeding around highlights. The dial sets the filter wavelength. AERO โ Kodak Aerochrome false color. Vegetation turns red, everything else keeps its neutral tone. The dial moves through the Wratten filter series (#12 to #25), exactly the axis practitioners used on the real film. NIGHT โ infrared at night. Tungsten lights blaze, foliage burns red against a black sky. The dial sets how deep into red the film goes. The engine adapts to each photo's white balance automatically. MOON โ day for night. Shoot in daylight, get a moonlit night โ the way the eye actually sees in the dark: reds sink first, color drains, the day sky goes deep. Not a blue wash. The dial sets how far into the night you go. FILM BACK FOR VIDEO Load a clip. The deck tunes on a poster frame, live; one key renders the whole clip in the same film โ every frame through the full engine. INSTRUMENT, NOT APP One aluminum deck. A tuning ruler, an exposure dial, one red key. Live rendering while you drag. Tap the nameplate to read what infrared light actually is โ with Herschel's 1800 experiment you can run with your finger. Exports in 10-bit HEIF at full resolution. No account. No network. Your photos never leave the device.
