ApolloOne

HDR Display & Export

See your RAW files with full dynamic range on HDR-capable Macs^* — 10-bit color, EDR-aware rendering, and a one-click HDR toggle in the toolbar. Filmstrip thumbnails render in HDR too, and a dual SDR + HDR histogram shows how much of your image pushes into the HDR highlight range. Export full HDR to AVIF or JPEG XL in PQ colorspace, gain-map JPEG and HEIC that stay viewable on SDR displays, or scene-linear OpenEXR. Supports HDR RAW, Apple gain-map HEIC/JPEG, PQ-encoded AVIF, JPEG XL, and OpenEXR.

HDR Visualizer

See exactly where your highlights push past SDR white. Four false-color bands — cyan at +1 EV, blue at +2 EV, purple at +3 EV, and magenta at +4 EV — overlay the image to show how bright each highlight actually is. Hover over any band in the histogram to isolate just that zone on the image.

Hover any pixel to read its per-channel value in the inspector's RGB patches — 0–255 for SDR, +X.X EV for channels that extend into HDR. Exact headroom, per channel, to a tenth of a stop.

Autofocus Point Display

See exactly where your camera focused. ApolloOne reads AF point data embedded in your RAW and JPEG files and overlays them directly on the image — so you can instantly verify focus accuracy without zooming in. It also displays faces detected by the camera from embedded metadata. A feature no other viewer offers.

Side-by-Side Comparison

Compare two images simultaneously with split view and synchronized zoom. Perfect for picking the best shot from a burst, comparing RAW vs JPEG, or evaluating different compositions — with full EXIF and map context alongside.

Deep EXIF & Metadata

Every detail your camera records, at a glance. A searchable metadata inspector shows EXIF, GPS, lens info, and more — alongside a full Places browser for navigating your photo library by folder or external drive. Double-click any editable field to change it on the fly — no separate dialog needed.

Tagging, Rating & Keywords

Organize your library the way you think. Add titles, descriptions, keywords, locations, and copyright — all written as XMP-standard metadata directly into the file. 5-star rate and color-label images for quick culling, with support for both XMP labels and macOS Finder color tags — so your tags stay visible in Finder too. Copy and paste metadata across files in batch.

Contact Sheet & Histogram

Browse hundreds of images in a thumbnail grid with RAW+JPEG pair badges and GPS indicators. Select any image to see full file details, camera settings, and a live RGB histogram — all without leaving the grid.

GPS & Built-in Maps

Every geotagged photo shows its location on an embedded Apple Maps panel with reverse-geocoded place names, coordinates, and altitude. Switch between Standard, Hybrid, and Satellite views — or search for any location directly from the map.

Google Street View

Go beyond the pin. Drop into Google Street View right from the sidebar to see the actual surroundings where you took the photo — no browser needed. Perfect for revisiting a location or scouting the area around a shoot.

Quick Edit

Non-destructive adjustments right inside the viewer. Tweak exposure, highlights, shadows, temperature, tint, contrast, saturation, vibrance, and unsharp mask — then export instantly with InstaBake™ via AirDrop or drag-and-drop. No round-trip to another app required.
