About

DDRM

Features
Read full description

DDRM is a digital darkroom for double exposures. On film, a double exposure was a happy accident: two moments on one frame, and you only saw the result once it was developed. DDRM brings that feeling back. Choose two photos, press DEVELOP, and the darkroom decides the rest: the blend, the placement, the light, the grain and the color. Not quite right? Develop again. No two takes are the same. SHOOT LIKE FILM • Shoot both exposures in the app. Your first shot stays on the viewfinder as a faint ghost, so you can line up the second. • Or pick either frame from your photo library. DEVELOP, AGAIN AND AGAIN • Every DEVELOP makes a new take, composed around the faces and light in your photos. • All your takes land on a contact sheet. Circle your favorites. • Surprise me picks a darkroom style for you. SIX DARKROOM STYLES Classic, Ghost, Bleach, Night, Dream and Accident: from a clean double exposure to wild, misregistered frames. FINE-TUNE WHEN YOU WANT TO ADJUST lets you move, scale and rotate the second frame, change the blend, and tune opacity, exposure, grain, warmth and color shift. Your adjusted version is saved as a new take, so the original stays on the contact sheet. REAL FILM CHARACTER Grain, halation, bloom, vignette, fade and color shift, rendered on your iPhone's GPU. SAVE AND SHARE • Save high-resolution prints to Photos. • Share as Film: a 4:5 feed or 9:16 story frame with a film caption. • Location is never included in the photos you save or share. PRIVATE BY DESIGN Your photos are developed on your iPhone and are never uploaded. No account needed. New to double exposures? Start with a sample pair and get your first print in seconds.
