Celvion Stack

Stack RAW and standard photos directly on iPhone or iPad—no computer required. Six dedicated modes, on-device AI denoise, lens correction and full-resolution export.

Turn a series of frames into a cleaner, richer photograph—right on your iPhone or iPad. Celvion Stack brings a complete stacking workflow into the field, so you can review, align, combine and export your images without waiting to get back to a computer.

CHOOSE THE RIGHT STACK FOR THE SCENE • Night: combine multiple exposures for cleaner low-light detail. • Milky Way: align the stars while protecting the landscape and reducing unwanted trails. • Light Trails: build continuous light paths from a sequence of frames. • Silky Water: blend movement into smooth water and cloud textures. • Object Removal: suppress people, vehicles and other moving distractions across a series. • Landscape: combine frames for a more refined, natural-looking result.

A MOBILE WORKFLOW THAT RESPECTS YOUR FILES Work with supported RAW/DNG files or standard photos. Automatic and manual lens correction can help address distortion, vignetting and chromatic aberration when a matching profile is available. Inspect the result, fine-tune the look and keep the output at the resolution your project deserves.

FINISH ON DEVICE Use on-device AI denoise to clean up challenging images, or AI super resolution when you need more output detail. Export to JPEG or PNG for everyday use, 16-bit TIFF for an editing-friendly master, or 10-bit HEIF for an efficient high-quality file.

YOUR PHOTOS STAY PRIVATE Processing happens locally on your device. Your source frames are not uploaded to a remote processing service.

AI features require iOS 18. Core non-AI stacking and editing features support iOS 17. RAW compatibility varies by camera and file format.
