Zeus Focus Stacking vs Celvion Stack

Every Pixel. Razor Sharp. Zeus Focus Stacking turns your iPhone into a professional macro lab. Capture multiple frames at different focus distances, blend them into one perfectly sharp image — front to back. PRECISION CAPTURE • Focus Range — set Near and Far brackets on the live preview, so each stack sweeps only the depth you want • Tap to rack focus straight to any subject plane • Automatic focus bracketing — sweep from near to far in seconds • 10 or 20 frames per stack (20 with Pro) • Linear or macro-biased focus distribution for optimal coverage (macro with Pro) • Capture Speed — Max Speed, Balanced, or Max Quality for the focus bracket (Pro) • Ultra 48 MP — capture the whole bracket at the sensor's full resolution, on iPhones with a 48 MP-class sensor (Pro) • Lossless 12 MP zoom via the wide camera • Shoot in portrait or landscape — your photo always comes out the right way up INTELLIGENT ENGINE Advanced focus-stacking built for iPhone. Smart alignment holds your frames in register through hand-held movement, lens breathing and focus shifts, and the engine renders them into a single image with finer detail and cleaner edges than any Zeus release before it — clean outlines where your subject meets the background, no glow around bright points, and no doubling when something shifts between shots. Core stacking runs on-device; optional iCloud sync and showcase uploads stay under your control. BUILT-IN EDITOR • Exposure, contrast, highlights, shadows, color and vignette — every change stays adjustable, and your original stays safe • Crop and straighten • AI object removal — paint over a distraction and it disappears (Pro) • 2× Super Resolution — double the resolution for galleries and large prints (Pro) PRO • Capture Speed — pick Max Speed for near-instant brackets (lighter per-frame processing) or Max Quality for the most per-frame detail; every stack exports at full resolution • iCloud Sync — projects and original frames across all your devices GALLERY THAT KEEPS UP • Original frames preserved for every project — re-stack with newer engines anytime • HEIC and JPEG export, native Photos sharing • Picture of the Week — submit your best focus stacks to the gallery TUNED TO EACH iPHONE Each iPhone model gets its own calibration profile, so the stacking engine knows exactly how your lens behaves. Sharper alignment, no manual tweaks. Macro photography. Product shots. Jewelry. Watches. Coins. Insects. Botanical specimens. Forensic detail. Whatever the subject — Zeus Focus Stacking handles depth so you don't have to. Free to download. Pro upgrade unlocks full-resolution export, Ultra 48 MP capture, AI object removal, 2× Super Resolution, iCloud sync, Capture Speed control, and 20-frame brackets.

Turn a sequence of frames into a cleaner, richer image—entirely on your iPhone or iPad. Celvion Stack gives photographers a complete local workflow for importing RAW/DNG or standard photos, inspecting frames, aligning, stacking, editing, and exporting without a computer. SIX PURPOSE-BUILT STACKING MODES NIGHT Combine multiple exposures to reduce random noise while preserving natural detail and color. MILKY WAY Align the sky and foreground separately so stars can remain sharp while the landscape stays stable. LIGHT TRAILS Blend selected frames into continuous, controlled light trails. SMOOTH WATER & CLOUDS Build a long-exposure look from a sequence, with smoother motion and flexible control. MOVING DISTRACTION REMOVAL Suppress people, vehicles, and other transient elements that appear in only part of the sequence. LANDSCAPE Merge aligned frames for a cleaner, more detailed landscape result. PRO MILKY WAY CONTROL Choose a reference frame, review per-frame quality scores, refine sky/foreground masks, and reject trails from aircraft and satellites, plus other intermittent light streaks, before stacking. RAW LENS CORRECTION When a matching lens profile is available, correct geometric lens distortion. Automatic vignetting and chromatic-aberration correction are not currently included. FULL-RESOLUTION EXPORT Export the final stack as JPEG, PNG, 16-bit TIFF, or 10-bit HEIF, then save it directly to Photos or Files. ON-DEVICE AI On supported devices running iOS 18, use local AI denoise and 4× super resolution. Core stacking works on iOS 17. PRIVATE BY DESIGN Processing stays on your device. Your photos are not uploaded.
