HDR Converter is a derivative product of the Prismatik app, designed to create a professional, easy-to-use, clean, and aesthetically pleasing HDR simulation and conversion tool. HDR Converter provides professional-grade HDR processing tools—from the brilliant transformation of SDR to HDR, to seamless conversion between multiple HDR formats—all completed offline on your device with 100% privacy protection. It is also optimized for Xiaohongshu (RedNote), making your posts stand out. Core Features --- HDR Simulation — Breathe New Life into Every Image Whether it's digital photography, classic artwork, or AI-generated content, HDR Simulation infuses images with realistic brightness and tonal depth. Built on Apple's official HDR Gain Map pipeline with targeted optimizations, it ensures every exported HDR photo has accurate luminance mapping and full metadata support. Smart Algorithm, One-Tap Simulation: Default parameters are automatically calculated based on in-depth image analysis, preserving natural light relationships while enhancing depth, luster, and spatial presence. Professional Manual Controls: Three core parameters—Highlight Boost, Highlight Range, and Peak Headroom—are provided, adhering to professional photography standards to reshape light with precision, not brute-force brightening. Platform-Specific Optimization: Tailored for Xiaohongshu (RedNote) and Instagram, ensuring your HDR work retains its stunning visual impact after upload. Efficient Batch Processing: Supports multi-task queue management, allowing you to add photos at any time and export individually or in batches. --- HDR Conversion — Break Down Format Barriers Say goodbye to HDR format incompatibility. HDR Converter fully supports bidirectional conversion across all major HDR standards. Supported formats include: Apple HDR (HEIF / JPEG): Perfectly compatible with the Apple ecosystem. Apple HDR (Compatible/HEIF): Optimized specifically for platforms like Xiaohongshu (RedNote), solving the issue of HDR loss after upload. ISO Gain Map (HEIF): A universal mapping standard compliant with international specifications. ISO HDR (PQ / HLG): Covers both broadcast-grade and consumer HDR standards—for example, .hif (HLG) files from Nikon Z cameras can be converted to Apple HDR (Compatible/HEIF) and shared directly to Xiaohongshu. All conversion processes preserve original metadata and support both Display P3 and sRGB color gamuts, meeting every need from professional review to social sharing. --- Privacy & Security We adhere to a strict "data localization" policy. All image processing is completed offline on your device—no uploads of any kind, no tracking components. Your work stays yours.

ScopeKit turns iPhone into a professional field toolkit for imaging and measurement. Whether you need to check distance before a shot, visualize depth information, or save ProRAW files directly to Photos or external storage, ScopeKit brings these capabilities together in a clear, focused interface that is ready when you are. Key Features Apple ProRAW Capture Manually control ISO, shutter speed, focus, and white balance. Save ProRAW DNG files to Photos or external storage for smoother field capture and post-production workflows. LiDAR Center Measurement Read distance from the center point of the frame, with modes for distance, height, and speed to make on-site judgment faster and more intuitive. Depth Preview and Color Mapping Convert depth data into a readable color image. Customize near, mid, and far colors, and save the current depth frame for review and reference. Simultaneous Front and Back Recording Use the front and back cameras in the same session, and manage preview layout, codec settings, and file-saving behavior. Photos and external storage are both supported. Quick Launch with Camera Control Supports Camera Control for faster access to the mode you use most. Designed for Field Work Reduce switching and repeated steps while shooting, measuring, scouting, and documenting. ScopeKit organizes multiple system-level capabilities into a more efficient workflow. Please note: Some features require supported iPhone models, camera hardware, or system capabilities, including Apple ProRAW, LiDAR, depth data, and Camera Control. Feature availability varies by device.
