Release notes: v3.1.2

v3.1.2 brings the RAW-develop V3 line to Windows for the first time. The Mac side adds a folder-marker fix and Loupedeck live-control integration; the Windows side ships a Nikon SDK based RAW develop path. See the feature comparison page for the Mac vs Windows differences.

New

• V3 (RAW develop) — first Windows release Windows: v3.1.2 brings the V3 RAW-develop line to Windows (x64) for the first time. All features are available except the Mac-only ones (HEIF edit / export, AI critique, AI search, DaVinci Resolve send). See feature comparison for details.
• LibRaw / Adobe DNG SDK develop on Windows Windows: The Windows build ships the same LibRaw + Adobe DNG SDK develop engines as the Mac build. Supported RAW formats: NEF / NRW (Nikon), ARW (Sony), DNG (Adobe / iPhone ProRAW), RAF (Fujifilm), CR3 / CR2 (Canon), ORF (OM / Olympus), RW2 (Panasonic), PEF (Pentax). DNG is developed via Adobe DNG SDK; everything else uses LibRaw direct. No extra installation required — all 19 sliders and exports work the same as on Mac.
• Nikon SDK on Windows Windows: The Windows build now ships a Nikon RAW SDK develop path for NEF / NRW, matching the Mac behavior. Authentic Nikon color including Picture Control is now available on Windows as well. Switch between LibRaw and Nikon SDK from the same "Nikon Default Engine (NEF)" setting.
• Loupedeck CT / Live integration: PonZCV can now be driven from Loupedeck devices through a plugin. EditMode sliders, ratings, color labels, C.TAG, and A/Z navigation can be mapped to physical knobs and keys. To install, open the Loupedeck desktop app (6.3 or later) and double-click "Loupedeck_PonZCV-Plugin-1.0.0.lplug4".

Bug fixes

• Folder marker creation on registration: A newly registered folder could miss its ponzcv.dat marker, which is required for relink. The marker is now created reliably on registration.

Release notes: v3.1.1

v3.1.1 is a maintenance release on top of v3.1.0. It adds direct export to the macOS Photos.app as a destination, and fixes the post-rotation crop / spot-fix bugs.

New

• Destination = Photos.app macOS: The export dialog now offers a Destination toggle between Folder (the existing behavior) and Photos.app. When Photos.app is selected, the rendered file is handed straight into the macOS Photos library and the Output Folder is ignored.

Bug fixes

• Crop ratio after a 90° / 270° rotation: Picking a 1:1 / 4:3 / 3:2 / L / 16:9 / orig preset right after rotating the image used to compute the rect against the pre-rotation aspect, producing a thin slip-shaped frame. The crop now matches the rotated composition.
• Spot-fix coordinates after rotation: Reference and apply points for spot-fix could land at the wrong source-pixel location while the image was 90° / 270° rotated. The transform now follows the rotated display correctly.

Release notes: v3.1.0

v3.1.0 rolls up the major additions since v3.0.3. The main themes are multi-window workspaces, stronger culling with C.TAG / stacks, 10-bit HEIF / HIF editing, HEIF export from RAW/DNG, and Max MB export.

Multi-window and workspaces

• Multi-window support (Preview / Edit): Turn on Settings → Display → Multi-Window to open the selected file's Preview / Edit in a separate BrowserWindow while the thumbnail browser remains visible. Movies still launch in the existing native player. Ratings, color labels, edit parameters, and per-file LUT changes auto-sync between windows in real time.
• Workspaces: The Window menu can save named main + secondary window positions and sizes. The workspace list shows the saved display layout and highlights entries that match the current monitor setup.
• Priority workspace cycle button: Mark up to 3 workspaces as pinned, then cycle through them from the monitor-icon button in the main toolbar or secondary window title bar.
• Restore and sync: The app can restore the last window layout on launch. AF points, index numbers, sort order, filmstrips, ratings, color labels, edit parameters, and LUT settings sync between windows.
• Preview / Edit while keeping the grid: With Multi-Window on, Space / double-click / Cmd+E route to the secondary window and keep the main window as the grid.

Culling and classification

• C.TAG (custom tags): Classify portraits, live-event shots, group cuts, and other folder-hostile sets with 3-letter tags, colors, and descriptions. You can define up to 50 tags; each file can hold up to 5 custom tags.
• Tag assignment and filtering: Assign tags from the palette, remove individual tags, or clear all tags. The FilterBar supports C.TAG AND / OR matching, No Tags, Select All, and Clear.
• C.TAG shortcuts: By default, Cmd+1–9 assigns tags 1–9 and Cmd+0 clears custom tags. A setting can make the number keys prefer C.TAG instead.
• Stacks / Nikon Z Burst Auto Stack: Consecutive visible files can be stacked manually. Nikon Z stills with BurstGroupID metadata can be auto-stacked by same folder, camera, and BurstGroupID within a 5-minute span.

Edit and export

• Native 10-bit HEIF / HIF edit: .hif / .heif / .heic files can now enter EditMode and export back to 10-bit HEIF. This supports HIF workflows from cameras such as Fujifilm X100VI while keeping originals untouched.
• 10-bit SDR HEIF export from RAW/DNG: Any source that can be edited through the 16-bit Nikon SDK / LibRaw / Adobe DNG SDK / native HEIF path can now export as HEIC 4:2:2 or HEIC 4:2:0, not just JPEG. Nikon HLG NEF exports as HDR HEIF in Nikon SDK mode; regular RAW/DNG/HIF/HEIF/HEIC sources export as SDR HEIF.
• Max MB export: Export quality now includes Max MB. Set a target of 1 MB or higher and PonZCV accepts only candidates that are at or below that limit. If even the minimum quality cannot fit, export fails instead of creating an oversized file.

Other

• Auto exposure on first LibRaw decode: RAW files developed via LibRaw (NEF/NRW/ARW/CR3/CR2/RAF/RW2/ORF/PEF) used to look darker than the embedded JPEG. PonZCV now compares the embedded JPEG and LibRaw default medians on first Edit / Export and adjusts automatically. Sliders stay at zero, and the correction also applies to Export.
