Chromaform

A professional RAW editor with on-device AI: remove objects, mask with a tap, relight, and color grade. Fast, and your photos stay on your device.

Chromaform is a professional-grade RAW photo editor for photographers who demand precision, speed, and total creative control — with a full suite of on-device AI tools that never send your photos to the cloud.

REAL-TIME RAW EDITING Open DNG, CR3, NEF, ARW, and other major camera RAW formats with true RAW processing. Exposure and recovery work directly from sensor data — no clipping, no compromise. Every adjustment renders live on the GPU through a Vulkan pipeline (vkdt + MoltenVK) and Metal-accelerated Core Image.

COMPLETE ADJUSTMENT TOOLKIT • Light: Exposure, Contrast, Highlights, Shadows + an interactive per-channel Tone Curve • Color: Temperature, Tint, Vibrance, Saturation • Effects: Texture, Clarity, Dehaze, Vignette • Detail: Sharpening, Noise Reduction, and Neural Denoise • Optics: Chromatic Aberration removal Fine-tune any slider with +/− buttons and reset any section with one tap.

COLOR GRADING Cinema-style color wheels for shadows, midtones, and highlights. Grade the whole frame, or apply grades selectively to the foreground, background, or a gradient region.

ON-DEVICE AI TOOLKIT • Generative Erase — remove unwanted objects and let the model paint in a clean background • Smart Masking — tap any subject to select it with Segment Anything Model 2.1, then adjust just that region • Recolor Clothing — automatically detect garments and recolor them to any hue • Relight — add up to five virtual lights and drag them across the scene to reshape the lighting • Portrait — face-aware adjustments • Match — transfer the look of any reference photo with neural analysis • Auto Adjust — one tap analyzes the scene with Apple's Vision framework (classification, face detection, saliency) for optimal exposure, white balance, and color

MASKING & GRADIENTS Combine subject masks with linear, radial, and rectangular gradient masks. Paint masks in or out by hand, feather the edges, and apply any adjustment or color grade to the masked area only.

PRESETS & LUTS Nine built-in looks: Natural, Vivid, Film Warm, Film Cool, Cinematic, B&W Classic, B&W High Contrast, Vintage Fade, and Matte. Import your own .cube 3D LUTs for custom film emulations.

CREATIVE EFFECTS Add atmosphere with the Water tool — rain drops and streaks.

PIPELINE CONTROL See every stage of the processing pipeline and toggle any phase on or off to understand exactly how your edit is built.

CLIPPING VISUALIZATION Toggle the Clip overlay to see blown highlights (red) and crushed shadows (blue) — essential for exposure-critical work.

NON-DESTRUCTIVE WORKFLOW Your originals are never modified. Edits are stored as lightweight recipes — reopen any image with your edits intact, or reset to original at any time.

PROJECT-BASED ORGANIZATION Group photos into projects, rate with stars, filter by rating, and copy, paste, or batch-apply edit recipes across an entire shoot. Review full-screen in the loupe with pinch-to-zoom.

PRIVATE BY DESIGN The entire pipeline runs on-device with MoltenVK and Metal. Your photos never leave your device.
