ApolloOne 4.5.0

May 12, 2026, 6:37 PM

Improved HDR rendering. AirDrop InstaBake™ HDR file transfer. Hasselblad X2D II 100C support.

  • NEW! SDR Proof Mode — live preview of how your HDR RAW will look as a plain SDR export. Toggle from the RAW menu, press ⌃⌘S, or click the "→ SDR" toolbar button.
  • NEW! HDR Slideshow — slideshow now displays HDR images in their full HDR brightness on EDR-capable screens. Supports HDR RAW (in HDR Mode), JPEG XL, AVIF, gain-map HEIC/JPEG, and HDR TIFF.
  • NEW! Quick Edit HDR adjustment sliders — three per-image sliders on Quick Edit's HDR tab: Highlight Contrast shapes the filmic curve in bright areas, Sky Enhancer adds saturation to blue skies, and Sunset Enhancer adds saturation to warm orange and red regions. Saved per image alongside other Quick Edit adjustments.
  • NEW! HDR-aware InstaBake™ — drag-and-drop, Share, and AirDrop now preserve HDR by writing JPEG with a gain map.
  • NEW! Use Apple Colors — optional continuity setting (RAW menu) that switches RAW rendering back to Apple's tone curve in either SDR or HDR Mode, matching the look you remember from Apple Preview or earlier versions of ApolloOne.
  • NEW! Canon DPP HDR .HIF (PQ) support — ApolloOne can now open Canon Digital Photo Professional-created HDR .HIF files encoded in PQ color space.
  • NEW! Hasselblad X2D II 100C support via RawBridge™ — full Apple-RAW pipeline coverage on macOS Sonoma and Sequoia. LibRaw fallback for older systems.
  • Enhanced HDR rendering — adaptive tone mapping matches each image to your display's actual headroom for faithful highlight detail on every EDR-capable Mac. New ApolloOne color science recovers more highlight detail and renders cleaner highlight colors than Apple's default RAW tone curve.
  • Updated ExifTool to version 13.58.
  • Performance improvements and bug fixes.
