Lumen Darkroom

A calm, private photo editor

$19.99

Lumen Darkroom is a focused photo editor for iPad that keeps your work clear, local, and reversible. Bring in a photograph and shape it with precise tools for light, colour, detail, crop, rotation, and masking. Your original stays preserved while every change remains part of a recoverable edit history. Built for the tablet, not shrunk onto it: • A single touch drives whichever tool is in your hand, with hand, move, marquee, lasso, zoom, select subject, paint, sample, and type. • Apple Pencil pressure feeds the brush engine directly, modulating tip size and flow as you draw. • Two fingers pan and zoom, a two-finger tap undoes, and a long press opens the full context menu. • Attach a keyboard and every desktop shortcut is there. Made for thoughtful, hands-on editing: • Adjust exposure, contrast, RGB and per-channel tone curves, temperature, tint, saturation, and vibrance. • Inspect the red, green, or blue channel as a grayscale plate on the canvas. • Develop supported camera RAW files with controls for exposure, white balance, detail, noise, and local tone. • Refine detail with sharpening, blur, vignette, film grain, and monochrome controls. • Crop, rotate, and flip with predictable output. • Paint, erase, clone, and heal on editable pixel layers with procedural brush tips, symmetry, and dodge and burn. • Select a foreground subject and export it as a transparent PNG. • Read a live histogram and sample RGB or LAB colour values. • Organize your work with layers, masks, blend modes, visibility, opacity, snapshots, undo, redo, and history travel. • Save a complete .lumen document with the source image, edit history, preview, and selection mask. • Keep documents in iCloud Drive and open the same document on your iPad and your Mac. • Export colour-managed PNG, JPEG, TIFF, and HEIC files, or add the result straight to your photo library. Lumen uses native Apple technologies and does not upload your photographs. Your files stay on your iPad unless you choose to export or share them. There is no account and no login. Lumen on iPad is landscape and requires an iPad running iPadOS 17 or later.

Accessibility - Text follows your text size on iPhone and iPad, up to the largest accessibility sizes. At those sizes the iPad switches to the single-column editor, so nothing is cut off. - VoiceOver and Voice Control: every slider, curve point, look and layer has a name, and sliders and curve points step up and down. - Clearer contrast: all text reads at 4.5:1 or better. - Reduce Motion now turns off every slide, fade and pulse. Fixes - The Looks sheet has a Done button, and the slider bar has Close. - Export on iPad no longer cuts off Save to Files and Save to Photos.
