About

Aeblyz

Features
Read full description

Aeblyz Studio brings uncompromising, desktop-class focus stacking and advanced macro metrics straight to iPhone, iPad, and Mac under a single Universal Purchase. Built exclusively on native Apple frameworks, Aeblyz directly unleashes the GPU power of modern Apple Silicon to merge focus brackets into single, high-fidelity master images with infinite depth of field and pristine edge-to-edge sharpness. ZERO-COPY WORKFLOW & NATIVE RAW FORMATS Aeblyz reads your asset files directly from their source paths (Files app or Photos library) without copying or duplicating data. It natively ingests high-megapixel formats supported by the underlying Apple platform: HEIF, CR2, NEF, FFF, and more. Computations are dynamically throttled to regulate thermal profiles safely, protecting your hardware and battery health. CORE COMPUTATION ENGINES: Zero-Allocation Tiling: Splits heavy images (up to 100MP+) into chunks, processing them in isolated sub-batch windows to keep memory usage flat. Precision Focus Heatmap: Fuses pixel-level sharp edge winners into a high-contrast spectrum overlay. Heatmap colors match your filmstrip thumbnail borders to identify exact frame source pixels. Decoupled Analytics Telemetry: An independent, orthogonal background pipeline. Toggle it off for rapid silent blending, or on to populate a real-time data ledger tracking Focus Coverage (%), Depth Expansion multiplier (x), and frame-by-frame contributions. All settings, presets, and adjustments are baked straight into exported file metadata. To restore your entire darkroom setup, simply pick that single focus-stacked image to reload parameters automatically. ADVANCED ADJUSTMENTS & TIMELINE SEQUENCING Standard presets work brilliantly out of the box, while comprehensive manual tools allow total macro control: Target Scene Profiles: Toggle between Standard, Low Light, Outdoor, and High Contrast.Exposure Tuning: Refine the stacked image exposure by precise 1/2 or 1/3 EV steps .Pre-Stacking Alignment: Hardware-accelerated Translation, Affine, and Homography registration models with built-in Deghosting to eliminate artifact shifts. Stacking Domain Priorities: Favor Blended Media, Text, Bokeh, or Sharp Graphics. Tactile Sequencing Carousel: Drag-and-drop unique color-coded, #numbered frames to rearrange your stacking order instantly, or untick individual checkboxes to exclude problematic images from the calculation. iPhone & iPad Touch Canvas: Gesture-isolated touch target zones override tablet multi-window cross-talk, ensuring silky-smooth multi-touch pinch magnification, panning, and long-press original reveals. Export masterworks in uncompressed 16-Bit Adobe RGB TIFF or 10-Bit Display P3 HEIF with Adaptive Alpha Conditioning—selectively stripping alpha bytes from opaque photos to slash file decoding sizes by 50% on disk.Transform your focus brackets into macro masterpieces with the raw performance and thermal protection of Aeblyz Studio.

The call
