ARK Infrared

Two new films: CYANO and COPPER TONE. CYANO is the cyanotype, the iron print John Herschel published in 1842. Paper coated with iron salts turns Prussian blue where light falls on it. CYANO prints your photo in a blue measured from real cyanotypes. The dial is the printing time. Press and hold the print to tone it to sepia and then back to the original photo. COPPER TONE is the red print. Copper toning turns the silver of a black-and-white print into copper ferrocyanide, which is red. Kodak listed it in 1918 as Tone A. The paper stays white. The dial is the toning time. Hold the print to see the silver print under the toner. Photos now open as their original HEIC instead of a re-compressed copy. RAW files develop at full bit depth, so skies are smoother, and Sony ARW files that would not open now develop. Saved prints keep the date, place and camera of the original, so they sit next to it in Photos. Swipe the film name to move through the films. Switching films is faster. Dark branches against the sky no longer get a thin light outline.
