A focused black-and-white photo lab for iPad: shape tone, grain, filters, curves, local adjustments, presets, and full-res exports with intent. Achroma Lab is a monochrome photo editor built for photographers who think in light, shadow, texture, and tone. Import images from Photos, Files, drag and drop, or supported RAW formats, then work non-destructively. Your original image stays intact while every adjustment remains editable, reusable, and ready for full-resolution export. Shape black-and-white images with a precise darkroom-inspired toolset: exposure, contrast, highlights, shadows, clarity, RGB channel mixing, photographic color filters, toning, curves, grain, vignette, sharpness, crop, and alignment. For more deliberate edits, add local radial points or graduated adjustments to guide brightness, contrast, and structure exactly where the image needs it. Compare before and after, move through a filmstrip, undo and redo changes, and copy edits across photos when a series needs a consistent voice. Achroma Lab also includes a built-in library for organizing work with favorites, smart collections, custom collections, filtering, sorting, EXIF-based browsing, and adjustable grid density. Create your own presets from finished edits, choose which adjustment groups they contain, and import or export preset JSON for a portable monochrome workflow. When the image is ready, export to Photos or Files as HEIF, JPEG, or PNG, with quality controls, optional metadata preservation, GPS removal, and Display P3 HEIF output. Achroma Lab is not a pile of filters. It is a quiet, precise workspace for black-and-white photography.
