About

HDR Merge Pro

Features
Read full description

Create editable HDR DNG files from bracketed camera RAW photos—right on your iPhone, iPad, or Mac. HDR Merge Pro combines multiple exposures of the same scene into one high-dynamic-range Digital Negative (DNG), ready for continued editing in a compatible RAW editor. It is designed for photographers working with real estate, interiors, architecture, landscapes, and any scene where a single exposure cannot capture the full range from shadows to highlights. FREE SINGLE-BRACKET WORKFLOW The complete single-bracket workflow is free. No subscription is required for single-bracket merging. • Merge one bracket of 2–3 RAW exposures. • Review your selected images before processing. • Follow clear progress through every stage of the merge. • Create one editable HDR DNG. • Save, share, add to Photos, or continue in a compatible RAW editor. OPTIONAL MONTHLY PRO Optional Pro unlocks Batch Merge for photographers who regularly process multiple scenes or larger brackets. • Import and process multiple brackets in one batch. • Merge brackets containing 2–7 exposures each. • Automatically organize images into recommended brackets. • Review and adjust every group before merging. • Process multiple groups efficiently while following both individual and overall progress. • Cancel a batch whenever needed. • Keep successful results even if another group cannot be completed. SPEND LESS TIME SORTING Choose your RAW images and let HDR Merge Pro recommend how they should be grouped. You remain in control: review the suggested brackets, remove unwanted images, and make corrections before processing begins. RELIABLE INPUT PREPARATION Import from Files, iCloud Drive, supported file providers, or connected storage. Once preparation is complete, temporary local working copies help protect your merge if the original cloud or external source becomes unavailable. Temporary files are cleaned up when they are no longer needed. SUPPORTED RAW FORMATS Compatible inputs include Canon CR2 and CR3, Nikon NEF, Sony ARW, and camera-original Bayer RAW DNG files. Compatibility may vary by camera model, recording mode, operating system, and destination app. OUTPUT DESTINATIONS Save completed DNG files to Files or Finder, share them using your device’s sharing options, add them to Photos, or open them in a compatible RAW editor such as Adobe Lightroom or Adobe Photoshop. Available destinations depend on your device and installed apps. PRIVATE, LOCAL PROCESSING Your RAW merge processing happens locally on your device. HDR Merge Pro does not require an account or upload your photos for processing. SUBSCRIPTION DETAILS Monthly auto-renewable subscription access is available as an optional Pro upgrade. The current price and billing period are shown before purchase. Payment is charged through your Apple Account. The subscription renews automatically unless canceled. You can manage or cancel your subscription in your Apple Account subscription settings, and Restore Purchases is available in the app. Adobe, Lightroom, and Photoshop are either registered trademarks or trademarks of Adobe in the United States and/or other countries.
