Halumo: Photo Editor

39 photographer-designed presets, one-tap subject and sky selections that run on your iPhone, and an AI that turns a sentence into real, editable adjustments.

Halumo is a professional photo editor built natively for iPhone and iPad. It brings together a deep collection of nondestructive light and colour adjustments, one-tap AI selections that run entirely on your device, 39 photographer-designed presets, and an AI that turns a sentence into a full set of real, editable adjustments.

Everything you need to finish a photograph

• Edit with a complete collection of nondestructive adjustments — exposure, contrast, highlights, shadows, whites, blacks, temperature, and tint • Shape contrast precisely with Tone Curves on RGB, Red, Green, and Blue • Edit colour exactly with an eight-band Colour Mix, tuning the hue, saturation, and luminance of each band on its own • Sharpen with radius and masking control, and reduce luminance and colour noise separately • Add a vignette, correct chromatic aberration, and apply lens-distortion correction to RAW files • Crop, straighten, rotate, and correct perspective • Follow every change in a live Histogram • Compare before and after with a split view, and step back through a compressed History and named Versions

Selections powered by AI

• Select the subject, the sky, or the background in a single tap • Press and hold any object in the photograph to select just that object • Add radial, linear, and brush masks, refine any selection by colour and luminance range, then invert, combine, and rename them freely • Paint at any Strength, and see exactly what a mask covers as a tint on the photograph • Every AI selection lands as an ordinary mask, editable with the same tools as one you drew by hand

Describe the edit you want

• Say what you want in plain words and get a full set of real, editable adjustments • Ask AI to adjust a mask you have already made, or to make a new selection for you • Ask for any of Halumo's built-in presets by name • Dial any result with Strength, ask for a Variation, or undo it outright • Turn on Visual AI when you want the model to read the photograph

39 built-in presets

• Apply presets designed for everyday, film stock, cinematic, night, portrait, landscape, and black and white photography • Preview any look on your own photo before you commit to it

Shoot, edit, and save

• Shoot with the built-in camera and open every frame for editing the moment you take it • Save a full-resolution copy back to your library and reopen it later • Share a JPEG anywhere • Opens HEIC, JPEG, PNG, WebP, screenshots, and RAW files
