Unlock the True Potential of Your Photos : raw2hdr transforms your camera's RAW files into stunning 10-bit HDR images that bring your photography to life. Whether you're shooting with a Sony, Fujifilm, Canon, or Leica, this app unlocks the full dynamic range hiding in your RAW files. What is 10-bit HDR? Standard photos are limited to 8-bit color (16 million colors). 10-bit HDR images contain over 1 billion colors — that's 64 times more color information! This means: * Brighter whites that truly shine without washing out * Deeper shadows with visible detail instead of pure black * Richer colors that match what your eyes actually saw * Glowing highlights in sunsets, city lights, and reflections Think of it like viewing your photos through a professional slide projector instead of looking at a print — everything has depth, luminance, and presence that jumps off the screen. The HDR Difference You Can See When you view HDR images on modern iPhones, iPads, or HDR-enabled displays, you'll notice: * Sunsets actually glow with warm radiance * City lights sparkle like real life * Black & white photos show brilliant whites that feel illuminated from within * Picture frames make your images pop off the screen with dimensional depth Perfect for Social Media - Share your HDR masterpieces where they'll shine: * Instagram - HDR photos stand out in feeds with eye-catching vibrancy * Threads - Your HDR images will stop the scroll * iMessage - Send HDR photos that look stunning on recipients' HDR screens * iPhone Photos - Full HDR viewing with the HDR badge Professional Editing Tools : * Histogram, Crop mode, Exposure, Contrast, Black Point, White Balance, Shadow Recovery, Lens Correction, Noise Reduction Black & White Conversion : * Transform your photos into luminous black & white images where whites actually glow brighter than standard photos. In HDR, monochrome photography reaches a new level — imagine viewing Ansel Adams prints with a backlight. Picture Frames & Borders : * Borders in any size with any colors * Custom aspect ratios (65:24 x-pan, 16:9, 4:3, 3:2, 1:1, or original) * Flexible alignment * HDR frames create a gallery presentation effect — like matted prints in a professional exhibition Simulations & LUTs: * Adding styles into your images in both SDR / HDR from ranges of 50+ styles Universal RAW Support - Apple's CIRAWFilter for professional-grade RAW processing Works with RAW files from major camera brands: * Sony (ARW) * Fujifilm (RAF) — including X-Trans sensors * Canon (CR2, CR3) * Leica, Apple, DJI, Google, Sigma, Ricoh (DNG) * Panasonic (RAW, RW2) * Hasselblad (3FR) * Olympus (ORF) * Pentax (PEF) * Nikon (NEF) * And many more... The Value of Converting to HDR : Your camera captures far more light information than what standard 8-bit photos can display. RAW files contain this "hidden" data, but you need HDR to actually see it. Standard Photo: Clipped highlights, crushed shadows, compressed colors HDR Conversion: Full dynamic range, glowing lights, rich shadows, true-to-life colors It's like the difference between looking through a dirty window vs. standing outside — suddenly everything is vivid, dimensional, and real. How It Works : 1. Import your RAW photos from anywhere 2. Convert to 10-bit HDR HEIC with a single tap 3. Editing with adjustments, add elegant frames, experimenting with film simulations 4. Share to Instagram, Threads, or save to Photos 5. Experience your photos in stunning HDR on compatible displays See the Difference : The difference between standard photos and HDR is impossible to describe — you have to see it. Once you experience HDR images on an HDR display, standard photos will feel flat and lifeless by comparison.

STB Camera is the free on-set companion to STB (Storyboard to Shoot). Take the director's board to the location and shoot a framing for every cut. ■ Frame by equivalent focal length Pick full-frame or S35, dial 10-600mm, and the viewfinder shows exactly that lens. Every iPhone adapts to its own lens set, and the physical switch-over points are marked right on the dial. ■ What you see is what you get Orientation is locked to the board's aspect, so a deliberate dutch angle is never auto-levelled. Tap to focus and meter, lock white balance, and apply B&W or high-contrast looks live in the viewfinder. ■ Compare on the spot A/B side by side, or blend the board over the photo. ■ Bring it back to STB Export the package and every photo matches its cut automatically. Scout shots can also go to Photos in three info styles, stamped with focal length, colour temperature and time. ■ No board? No problem Build one on set and it becomes a new film back in STB. Interface in Traditional Chinese, English and Japanese, switchable inside the app.
