02 / LOOK CLOSER
Match star fields, align astronomy images and inspect the differences. Linked views keep you oriented, while Astronomy Inspect offers Blink, Slider and Difference modes. Your original image files stay unchanged.

Illustrative subject tagThoughtful intelligence
Your photos hold more than filenames. Search for what’s in the frame, outline the subject that matters, and find related images across your collection.
Local face, animal and object matching suggests connections. You review the results and decide what belongs.
Region tags, automatic groups and Smart albums bring structure. Keep, Maybe and Reject help the best shots rise to the top.
Subject analysis happens on your Mac. Your photographs remain yours, and edits preserve your originals.
The beauty is in the detail
Compare images with linked views and precise alignment. For astronomy, go further with Blink, Slider and Difference inspection—try the controls below.
Drag the divider, or use the arrow keys, to compare the two views.
Astronomy Inspect controls illustrated with a colour-treated sample photograph. In MemoryLume, these modes compare selected astronomy images using their saved alignment and appearance settings.

One app. Two extraordinary ways to explore.
Follow your photos across the Earth—and your images into the night sky.

Turn your photos and images into Image Books with considered layouts, captions and rich text. Relive them in a tactile 3D reader or a simple single-page view, on Mac and iPad.
Book drafts are saved locally on each device.




Turn albums, tags and Smart albums into presentations, looping photo walls or Earth and sky tours. On Mac, send playback to a connected second display.
Mac offers all three playback modes. iPad includes Photo wall.Your memories are personal
Your photos and astronomy images can stay in their existing folders on your Mac or connected drives. MemoryLume brings them together through references, with local analysis and saved adjustments that preserve your originals.
Explore your privacy controlsWork with locally stored photos and images, and keep catalogue organisation on your Mac. You decide where your originals live.
Face and subject matching, description indexing and tagging run locally. Face representations are neither uploaded nor saved in the catalogue.
Online plate solving uploads a reduced preview only when enabled. Maps, reference imagery and cloud-only originals may need a connection.
Security starts with control. You choose where your collection lives, who can access your Mac, and how you back up your files.
Good to know
A few details before your
next chapter begins.
The full MemoryLume experience runs on Mac with macOS 14 or later. The iPad companion requires iPadOS 17 or later. Mac is where you organise, search, align and analyse your collection; iPad brings imported catalogues to a touch-first browsing experience, with photo walls and Image Books. The documented release supports Mac and iPad.
Yes. On Mac, add photos and images from Apple Photos, a computer folder, another app album or your current catalogue. MemoryLume normally references originals in their existing locations. It supports JPEG, PNG, HEIC, TIFF, supported camera RAW, native FITS, videos and Live Photos. RAW and video compatibility depends on macOS support.
Description indexing, face and subject matching, and tagging are processed locally on your Mac. Face representations are not uploaded or saved in the catalogue. Optional online plate solving sends a reduced preview to Astrometry.net only when enabled. Map imagery, reference images and cloud-only originals can require internet access. Local plate solving is available with separately installed solvers and databases.
Viewing, alignment, crop, curves and other saved display adjustments preserve your original image files. Albums and tags organise references to photos. The separate, explicit Delete from Photos action can delete an asset from Apple Photos; normal editing and removing catalogue references do not.
Export a portable catalogue from the Mac and import it into the iPad companion to browse an independent, offline copy. This is an intentional transfer, rather than automatic sync. Image Book drafts are currently local to each device and are not included in catalogue transfers, PDF or print exports.
MemoryLume is coming exclusively to the Apple App Store. The store listing, release date and pricing have not yet been announced. This page will link directly to the official listing when it is available.
