Mac

Rayloom is a photo and video workbench for the Mac: open a folder and see your RAWs, edit without touching the original, and turn a set of shots into a star stack, time-lapse or focus stack. OPEN AND LOOK • Camera RAW (DNG, NEF, CR2, CR3, ARW, RAF, RW2, ORF), HEIC, JPEG, PNG, TIFF, and MOV and MP4 video. RAW is decoded by macOS, so camera support grows with system updates • Add folders as sources and they stay; press ⌘O to open a few files and leave no trace when you close the window • Grid, single, compare and full-screen views; for RAW, compare the camera's embedded preview side by side with Rayloom's development • Sort by file name or capture time, ⌘-click and ⇧-click to select, double-click for single view SIX LAYERS, ORIGINALS UNTOUCHED • Optical: black velvet, black mist, white mist, star and streak filters; the star filter only puts stars on point lights • Tone: exposure, contrast, highlights, shadows, whites and blacks, plus luminance and red, green and blue curves you can drag right on the photo • LUT: built-in looks and Apple Log restore LUTs; import your own .cube files (up to 36), each tile a live preview on the current photo • Palette: eight style palettes plus a two-axis warm/cool and light/dark pad, with skin-tone protection • Texture: grain, fade and vignette, stackable with every other layer • Render: instant film, disposable, CCD and Classic CC looks, with colour and tone controls. Paper and frame are optional • All adjustments are saved as a recipe file next to the original, which is never modified; save a recipe as a preset A SET OF SHOTS, ONE RESULT • Stack: mean (noise reduction, smoothing water and crowds), maximum (star trails, light trails, fireworks) and star (rotational alignment on the stars for cleaner shadows) • Time-lapse video: plain, noise-reduction stack, clean-up stack and star-trail video, in 1080p or 4K at 30 or 60 fps • Focus stacking: combine a DNG focus-bracketed sequence into one photo that's sharp front to back • With RAW sources, stacks and focus stacks can be saved as a linear DNG to keep working in your RAW editor • Before you start, the grid marks which shots can't join the sequence and why VIDEO • Frame-accurate transport: Space to play, comma and period to step, J / K / L for reverse, pause and fast-forward, 0.25× to 2× preview speed • The filter layers work on video too; Apple Log and Apple Log 2 footage can have a restore LUT applied before grading • Zoom, compare and full screen as for photos; exports as HEVC ONE PANEL FOR EVERY EXPORT • Single, batch and combined results all go through one export panel: location, subfolder, file name, format and recipe, all in one place • Formats: HEIF (8-bit or 10-bit), 16-bit TIFF and PNG; combined results can also be saved as DNG • Batch export reads each file's own recipe, or applies one preset to all of them • Remembers your last location and settings — ⌥⇧⌘E exports again in one go; name clashes get a number, existing files are never overwritten • Exports run in a background queue; close the panel and pick the next batch • Write author, copyright, contact and usage terms into exported metadata PRIVACY • Offline: the sandbox has no network entitlement — no account, no ads, no analytics • Rayloom only reads the files and folders you choose, and all processing happens on this Mac FREE AND FULL VERSION Browsing, comparing, full screen, all six layers, recipes and presets are always free. Exporting and combining need Rayloom Full Version: a one-time purchase, yours for good, not a subscription.

Available in ten languages, following your system language. Requires macOS 26 or later.
