Backdrop
Read full descriptionHide full description
Pick a Look and the camera changes. Point it at a street and the street is already painted in oil, or broken into dots, or drawn by hand. You are not previewing a filter. That is the picture, and the shutter keeps it. THE LOOKS Brush. Painted stroke by stroke, coarse to fine, as you move. Mosaic. Rebuilt from its own colours. Cells split where there is detail. Drawn. The world drawn instead of photographed. Flat colour, inked lines. Matter. The picture as a field of grains that drift and settle. Fur. Combed strands that follow what the camera sees. Dither. Tone traded for dots on one fixed grid, nothing in between. Halftone. Print dots on a square or hex grid, in four shapes. Fluted. Seen through ribbed glass. The world arrives in strips. Water. Refraction and caustics, the scene read through moving water. Code. Digital rain over katakana, lit by whatever the camera sees. The list grows. New Looks arrive in updates. TAP OR HOLD Tap the shutter for a photo. Hold it to record, up to ten minutes. Video renders in the background at full quality, one frame at a time, using the exact settings you shot with. TUNE ANYTHING Every Look has its own knobs. Size, grain, relief, speed, depth, whatever that Look actually has. Drag the handle at the edge of the screen and the picture changes under your thumb. Tap a knob to put it back. BRING YOUR OWN Choose from Photos to run something you already have through a Look. For video, trim it first, pick the frame, then render. NOTHING LEAVES YOUR PHONE No account, nothing to sign in to. No servers. What you shoot sits in the Shelf on your device. Saving a copy to Photos is a switch, off until you turn it on. BACKDROP PREMIUM Dither, Water, Halftone and Drawn are free, and they record video too. Premium opens every Look, including the ones added later, and takes the Backdrop mark off everything you shoot.
