5.1 HDR Imaging Engine: Unleash Every Highlight Beyond the Screen Mobile HDR photography has long been stuck in crude global brightening or post-capture algorithmic compositing. In 5.1, we chose to build a complete Gain Map HDR imaging pipeline from scratch — enabling every ProRAW / BayerRAW photo captured by Gleam Camera to carry true Extended Dynamic Range data, identical in origin to Apple's system camera, lighting up precisely on EDR-capable displays. In this version, HDR is available exclusively in Film Mode shooting and the RAW Editor. Photos taken in Film Mode with ProRAW / BayerRAW automatically embed Gain Map HDR data; in the RAW Editor, you can toggle HDR on and off in real time via the HDR button, previewing highlight effects as you edit. Future versions will gradually expand HDR support to more shooting and editing scenarios. Native EDR Gain Map Extraction Rather than "guessing" highlights on an SDR image, we go straight back to the physical origin of the RAW data: Full-power CIRAWFilter EDR decoding: Extracts the linear-space highlight information that conventional pipelines clip away, precisely mapping the super-bright range into Gain Map grayscale values. Apple-Native HDR Metadata Injection Making the system Photos app and third-party apps truly "understand" our HDR — not just a brighter picture: MakerApple private tag injection: During HEIF encoding, we precisely inject Apple's private EXIF tags 33 (HDR Gain Map Version) and 48 (Display Headroom), enabling the system Photos app to natively recognize and render HDR highlights — identical to the system camera. 10-bit HEIF + Gain Map unified packaging: Using Core Image's hdrGainMapImage option, the Gain Map auxiliary image is embedded directly into the HEIF container — no extra files needed, losslessly preserving Extended Dynamic Range data. Real-Time EDR Preview in RAW Editor From "editing blind" to "what you see is what you get" — feel the highlights glow at every step of your edit: HEIF Round-Trip + UIImageReader true EDR rendering: Preview frames are encoded in real time as 10-bit HEIF carrying a Gain Map, then decoded back to UIImage via iOS 17 UIImageReader in prefersHighDynamicRange mode, paired with preferredImageDynamicRange to deliver true Extended Dynamic Range display on screen. Smart Gain Map caching: The Gain Map extracted from RAW on the first pass is cached as concrete pixel data (rather than a lazy CIImage chain), so subsequent adjustments only re-encode the base layer — avoiding repeated RAW decoding that causes lag and memory overflow. 5.1 is not simply about "making photos brighter." It is a complete HDR pathway built on mobile — from RAW physical signals to EDR pixels on screen. Every highlight, faithful to the light at the moment you pressed the shutter.

To achieve the ultimate "analog film look," we have completely overhauled our previous noise rendering logic and launched a brand-new, cinematic-grade film grain engine: 1. Luma Modulation Blend: Abandoned the hue-destructive RGB additive blending in favor of a more scientific luminance modulation. This ensures "red grain on red, green grain on green," completely solving the issue of muddy or grayish grain in solid color areas. The overall image clarity has been significantly enhanced. 2. Pink Noise & Clumping Simulation: Eliminated harsh high-frequency white noise, replacing it with a Gaussian approximation using 3-pass micro-offset sampling. The grain edges are now much softer, perfectly replicating the organic "clumping" texture of real silver halide crystals on film. 3. Dynamic Shadow/Highlight Protection: Rewrote the luminance response curve. Added unidirectional base noise compensation for shadows and an anti-clipping mechanism for highlights. This ensures that even at maximum grain intensity, you will never see "pitch-black spots" or "blown-out highlights."
