CHRO

CHRO is a camera for chromatic aberration: the red, green and blue fringes a lens throws off at bright edges, giving a photo or video a dreamy, filmic look. You see it live in the viewfinder, before you press the shutter. ONE GLASS STRIP, ONE TRAY OF TOOLS The strip under your thumb holds Look, Character, the shutter, Zoom and Adjust. Swipe the picture to change look; tap Character for the effect. Adjust opens one tray above the strip: Presets, Look, Character, Lens, Blur, Grain, Tone, Colour, Exposure, Focus and White balance. It is the same size for every tool and shows one slider at a time. Along the top, Flash, Timer, Live and Format open with a tap, and the gear opens Settings. PHOTO AND VIDEO Switch between PHOTO and VIDEO under the picture. In Photo, tap the shutter for a photo, or touch and hold it for a quarter of a second to record a short clip. In Video, the red shutter starts a clip with a tap and stops it with another. Format opens the choices for the mode you are in. MANUAL CONTROLS, WITH A LIVE READOUT Set shutter speed and ISO by hand, focus by hand, and white balance from four kinds of light or a colour temperature and tint; lock any of them where it is. A line at the top of the tray reads shutter, ISO, EV, focus and white balance live, in yellow where you set them. RAW, QUALITY AND VIDEO FORMATS Take Apple ProRAW (or RAW), or a HEIC with your look together with the RAW. Choose Speed, Balanced or Maximum processing, and 12, 24 or 48 megapixels where offered. Record video at 24, 25, 30 or 60 frames a second, as HEVC or H.264, at full size or 1080p, with stabilisation where offered. LIVE PHOTOS Turn on Live and each photo keeps about three seconds of motion and sound, saved to Photos as a Live Photo with your look on both. It is off until you turn it on. Open one from your library to put a look on the photo and its motion together. 22 LOOKS, AND YOUR OWN Film: fourteen looks inspired by classic film stocks. Filters: eight colour grades, from Neon and Dispo to Terra and Arctic. Add looks of your own from a .cube file; rename, hide or reorder any look in Settings. All are live and baked into what you save. CHARACTER, GRAIN, EDGES AND TONE Character sets the lens aberration, the soft edges and the film grain together: slide up and all three grow, down to zero and they are gone. Grain comes in four patterns, Fine to Heavy. Soft edges melt the picture toward the corners. Three lens styles: Classic, Scope and Vintage. Highlights, Shadows, Sharpness, Saturation and Contrast shape the picture. PRESETS Save a look and its effects as a preset with one tap: three to start with, up to twelve. Touch and hold to replace, share or clear one; a shared preset joins your friend's row when they open it in CHRO. EDIT AFTER THE SHOT Open any photo or video from your library or Files and give it the same looks. Hold the eye to compare. Crop, rotate, trim a video, export a copy: your original is never touched. Select up to 50 to put a preset on all of them. SHORTCUTS, LOCK SCREEN, IPAD Ten Shortcuts actions take a photo, record a video, open the camera, set a look, Character, grain, blur, a preset or Live, and put a look on photos and videos. Add CHRO's camera control to the Lock Screen or the Action button. On an iPad, and on a phone on its side, the camera and the editor fit the room they have. THE DETAILS • A one-minute tour on the live camera (the gear, then Show the guide) • Camera Control on iPhones that have it: look and Character • Send a photo or video from the Share sheet; it all works offline PRIVATE BY DESIGN No account, no ads, no tracking, no analytics. CHRO has no servers and never sends your photos or videos anywhere on its own: they stay on your device unless you share them. Camera and microphone are used only to show and record what you point it at, including a video's or a Live Photo's sound; Photos only to save your shots and open what you pick.
