Glass Half Full

Glass Half Full converts your negatives into photographs, a whole roll at once, and gives any photo the colour of real film. Underneath is a full photo editor for RAW, JPEG and HEIC files. Buy it once, with no subscription, no account and no ads. Everything happens on your phone or tablet. CONVERT YOUR NEGATIVES Photograph your negatives with a camera over a light, or with your phone over a light box, then import them. Glass Half Full finds each frame, crops and straightens it, and converts it, one frame or a whole roll at once. Colour negatives, black-and-white negatives and slides each have their own conversion. Choose how a colour negative is printed from previews of your own frame: Standard, Lab scan (measured from a real lab scanner), Darkroom print or Print film. Slides can be viewed and exported in HDR on Android 14 or later. BUILD YOUR UNIQUE LOOK Pick a film and see it on your own photo first. You don't need to shoot film: the films work on phone photos, JPEGs and camera RAW files. Natural films are modelled on real film stocks, starting from colour charts photographed on film and on a digital camera. Each has the film's grain and halation, and you can shoot them under or over and push or pull the development. Nostalgic films are softer and dreamier, for a light, airy feel. A FULL EDITOR UNDERNEATH Every tool works on a phone photo, a camera RAW and a converted negative alike. RAW files are developed from their sensor data, with any lens corrections they carry. Start with Auto, then adjust exposure, contrast, highlights, shadows, whites, blacks, clarity and dehaze. Set white balance, shape tone and colour with curves, fine-tune eight colour ranges with the colour mixer and grade shadows, mid-tones and highlights with colour wheels. Crop, straighten and correct perspective with Upright. WORK ON JUST ONE AREA Brighten a face, darken a busy background or bring back a bright sky with masks. Draw linear and radial gradients, paint with a brush, or select by colour or brightness. CHOOSE A LOOK Signature looks render the whole picture their own way, tone and colour together. Cinema looks set cool shade against warm light. Black-and-white prints run from glossy paper to selenium and platinum toning, with a colour filter. Looks work on film scans and slides too, and Surprise me picks one for you. FINISH IT LIKE A PRINT Add grain measured from real film scans, halation, bloom, light burn and a vignette. Sharpen, reduce noise with a standard or Neural method, remove colour fringes and repair dust. Put your photo on a strip of film, with natural edges or a full-sprocket border, or give it a paper texture and border. MORE TOOLS Carousel lays photos and text across slides that join as you swipe. Multiple exposure layers up to nine photos into one. Develop plans, times and logs your film development, with times from the makers' data sheets. ORGANISE EVERY ROLL Keep film scans together in rolls and gather photos into folders. Sort by date, mark picks and rejects, copy settings across a set and export in batches. Make a contact sheet of a roll, or a short video of it converting. Save settings as recipes, and share them as files or recipe cards. KEEP YOUR ORIGINALS Edits are saved separately and never change your originals. Compare with the original and undo any change. Export a JPEG to share or a 16-bit TIFF for further editing. Back up your library as a ZIP archive and restore it at any time. BUY IT ONCE Import and edit as much as you like for free, and export 12 photos at full quality with no watermark. Re-export those photos whenever you like, including in other formats. A one-time Full Unlock removes the export limit. No subscription, no account, no expiry. RAW support depends on your camera. I'm Sam. I shoot and scan film, and I built Glass Half Full for my own photographs. If something gets in the way of yours, I'd like to hear about it.

Colour negatives convert better, and light burn is now its own effect with a choice of colours.
