Folder-first browsing
Open local photo folders and move through JPEG, PNG, WebP, TIFF, BMP, GIF, and DNG files from one filmstrip.
A Windows-native workspace for browsing, adjusting, and exporting photos — without breaking your flow.
Lumen is designed around the real editing loop — open, adjust, retouch, export.
Open local photo folders and move through JPEG, PNG, WebP, TIFF, BMP, GIF, and DNG files from one filmstrip.
Set white balance, highlights, shadows, clarity, sharpening, vignette, and a five-band saturation curve.
Apply XMP presets and sidecars directly — your existing Lightroom library works without conversion or re-export.
Crop, selection mask, object removal, blemish cleanup, red-eye reduction, and teeth whitening.
Move from adjustments to a clean JPEG export without losing your selection or preset context.
Lumen is a desktop application built for Windows, giving you a dedicated editing room with native performance.
Three steps that cover the full editing cycle — from folder to finished image.
Point Lumen at a folder and start reviewing immediately. The library sidebar keeps your filmstrip visible while the canvas stays center stage.
Bring in presets, sidecars, or LUTs and stack tonal adjustments on top. Every edit stays non-destructive so you can explore freely.
Crop, retouch, and mask the details, then export a clean JPEG with your settings intact.
Lumen reads .xmp (Adobe XMP sidecars), .lrtemplate (Legacy Lightroom templates), .cube (3D LUTs), and .dng (DNG reference files). XML files are also supported and treated as XMP. Your existing Lightroom library works without conversion.
Place preset files in a folder named preset. Lumen searches these locations in order:
%LOCALAPPDATA%\Lumen\preset — the recommended locationpreset folder next to your photo librarypreset folder in the app install directoryYou can also open the Presets folder directly from the Lumen Start Menu shortcut.
Open a photo in Lumen, click Import Preset, and select your .xmp file. The adjustments are applied immediately and non-destructively. If a preset file has the same name as your photo and sits next to it, Lumen detects it automatically as a sidecar.
Yes. Lumen reads XMP sidecar files that Lightroom writes alongside your images. White balance, exposure, highlights, shadows, clarity, sharpening, vignette, and saturation curve adjustments all map directly to Lumen’s controls.
Lumen requires Windows 64-bit with the .NET 10 Desktop Runtime (x64) installed. A minimum display resolution of 1280 × 820 is recommended. The installer handles everything automatically.
