Mac

Cull large photo sets fast, then finish them: print/framed-style export, 38 design layouts, and per-color retouch. From RAW to export — all on your Mac. Postra is a Mac-only photo library that brings everything from choosing your shots, to building photo sets, to preparing posts for social media into a single workflow. — Rediscover the joy of "finding" your photos. No tagging required. Just open a folder, and Postra understands your photos automatically. [ Similarity search + keyword search ] - Search by meaning (CLIP) — AI surfaces photos that match a situation, like "sunset, sea" or "crosswalk, people." - Search by appearance (DINOv2) — perfect for picking the best frame from a burst, or grouping shots with the same tone. - Keyword search — type in natural language and search even without EXIF tags. "Backlight" or "red umbrella" just work. [ AI that gauges your best shots ] - Aesthetic score (NIMA) On import, every photo is given an aesthetic score from 1.0 to 10.0, color-coded as a relative ranking within the folder, so your best shots stand out at a glance. Fast on-device inference via the Apple Neural Engine. Note: This is a ranking within the folder, not an absolute rating. - Color harmony When a photo set has two or more slots, Postra evaluates tonal consistency in the Lab color space across three levels — in harmony / slightly off / not matching — so you can catch color clashes before export. [ Dual A/B layout ] 1, 2, 3, 4 photos, or a free layout. Split the layout panel in two to work in parallel with the same or different material. Supports common social ratios such as 1:1, 4:5, 16:9, and 9:16. [ Non-destructive retouch + color balance ] Your originals are never altered — adjustments are stored per photo. You can also balance color across an entire photo set. [ Blazing-fast scrolling ] Even with folders of tens of thousands of photos, Postra keeps pace with your fingertips. Its JPEG-first pipeline offloads thumbnail generation and Bayer development to the background, so the UI always stays smooth. [ Requirements ] - Apple Silicon Mac only (M1 or later) - macOS 12 Monterey or later With Postra, turn the time you spend choosing photos into time spent creating.

Postra Studio 1.4.0 — Save your whole look as one "Favorite." ■ Unified Favorites (new) Save your current setup — layout shape, design, mat, frame, shadow, paper, background, margins, caption, date stamp, and export size — as a single "Favorite" you can recall anytime. Your photo selection and retouching stay untouched, so you can apply the same finish to a different set instantly. Pick from a gallery with diagram thumbnails, plus ready-made shape templates. ■ Color tags & rating (new) Added five color tags and a "hold" state. Rate and tag multiple selected photos at once to sort large sets fast. ■ Free-edit frames on the board Drag layout frames directly on the board to resize and reposition them freely. ■ Export at original size Individual export can now output at the source image's full resolution. ■ Mat (passe-partout) Added a mat around photos for individual export and carousels — a framed, matted finish. ■ Output format (JPEG / PNG) Choose between JPEG and PNG when exporting. ■ Auto-wrapping caption band The framed caption's info line now wraps to the band width, so long text fits.
