Capture One 16.8.2 release notes

Denis Huk
  • Updated

Released on June 25, 2026, Capture One 16.8.2 is a service release that adds Multi-User Sessions (Beta), day-zero support for the Leica SL3-P, and file support for 24 Panasonic cameras.

Capture One 16.8.2 is backward compatible with Sessions and Catalogs created in previous 16.8 releases. Documents from Capture One 16.7.8 or earlier must be upgraded to open in Capture One 16.8.2. Once upgraded, they can't be opened in older versions unless restored from backup. Learn more about Upgrading a Session, Upgrading a Catalog, and Restoring from backup.

New features and functionality

Multi-User Sessions (Beta)

Teams can now work inside the same Session at the same time. Whether that's multiple operators on a high-volume e-commerce floor, or a photographer and their crew on a portrait or editorial shoot. No shared drives, no manual hand-offs, no single-machine bottleneck.

The beta is Mac only, and hosting requires Capture One Studio. Collaborators on any plan can join if invited, with Studio and Studio for Teams supporting up to two collaborators and Studio for Enterprise supporting an unlimited number.

Multi-User Sessions work over the local network, whether over Wi-Fi or wired (e.g., Ethernet over USB). To share a Session, go to File > Shared Sessions (Beta) > Share and Manage Session, add collaborators by their Capture One account email, and click Start Sharing. Collaborators join from File > Shared Sessions (Beta) > Find Shared Session and choose a local folder to save their copy on first join.

Capabilities are clearly divided between the host and the collaborators. As the host, you work exactly as usual with full control over the Session structure: managing imports, captures, tethering, folder creation, and file moving or renaming. As a collaborator, you receive full-resolution RAW files in real time and can freely create and edit variants, with your adjustments, ratings, color tags, and keywords instantly replicating across every screen. For a full breakdown, see Roles and collaboration limits.

If a collaborator drops off the network, they reconnect automatically after short outages. Closing Capture One is fine too, reopening the Session picks back up without going back to Find Shared Sessions. Any collaborator can convert their local copy to a standalone Session. This breaks the sync permanently but leaves a fully usable independent Session.

For details, see Multi-User Sessions (Beta). Since this is a Beta, we'd love to hear how it's working for you.

 

User experience and performance improvements

Delete unused Enhanced Denoise data

You can now delete all unused Enhanced Denoise sidecar files in one step. In the Noise Reduction tool, open the ... menu and select Manage Enhanced Denoise Data... > Delete.

AppleScript support for Subject, Background, and People Masking

AppleScript support has been extended to cover Subject, Background, and People Masking. You can create a mask from a script, target specific body areas, and generate separate mask layers per person.

4K monitors

For optimal performance on 4K monitors, we recommend doubling the initial specifications due to the increased computational demands. Additionally, investing in a high-performance GPU with ample VRAM is highly recommended for these configurations to handle the intensive graphics processing.

Recommendations and limitations

Note: The information provided here is subject to change and unintentional errors may occur. For any queries or further clarification, please contact support at https://support.captureone.com/

General guidelines

  • Browsing folders containing unsupported image files may affect application performance.
  • Previews from earlier versions of Capture One may be updated, which can affect the application performance the first time images are viewed in this version.
  • Using a non-US laptop keyboard might require changing some of the standard keyboard shortcuts.
  • Editing images in external applications other than Adobe Photoshop might result in unexpected behavior.
  • Operating under virtualization software (e.g., Parallels, Hackintosh, etc.) may cause instability. These OS configurations are not recommended.
  • Some cameras provide multishot functionality by way of multiple exposures or pixel shifting. In most cases, this functionality will not be available in Capture One. However, a single RAW file from the "stack" may be viewable and editable in Capture One (as if it was a shot in single Capture mode).
  • Special or auxiliary modes (like pixel shift) are only supported if noted. If the information provided is incomplete or you need specific information pertaining to support in Capture One, kindly reach out to Capture One Support at captureone.com/support.

File support

  • HEIC/HEIF support: Capture One supports HEIC/HEIF 8-bit files to the extent that the operating system supports the files. If you are on a Windows computer, you might need to download the two extensions "HEVC Video Extensions" and "HEIF Image Extensions" from Microsoft to enable support in Capture One.
  • Capture One DNG colors: DNG files from camera models with native support in Capture One will per default have their native Capture One colors applied. DNG files from camera models that are not natively supported in Capture One will have generic DNG Standard colors applied. Adjustments and settings from other applications embedded in DNG files are not supported.
  • Other file support: TIF/JPG/PSD/PNG files that are not in RGB color space cannot be adjusted within Capture One and will be read-only. Layered Tiff and PSD files can be supported for viewing purposes only. Reprocessing the image will result in a new flattened image.
  • File size limitations: The smallest supported file for viewing has a minimum side of 16 pixels. The smallest supported file for editing has a minimum side of 512 pixels. The largest supported file is 715 megapixels or 65,000 pixels on the longest edge.

Known issues

  • You can find a list of known bugs in a dedicated community forum topic titled Known Bugs. Note that this list may not be up to date on the day of a new Capture One version release.
