New Features and Functionality
Support for Grayscale Image Editing
Capture One now supports editing grayscale images, enhancing workflow flexibility.
For details, see TIF, JPG, PSD, PNG support.
XMP Crop and Rotation Sync
Capture One now respects crop and orientation settings stored in XMP from other software. Resetting crop or rotation in Capture One will revert to the values set in the external software, not the full-size, unrotated image.
Pack iPhone DNG Files as EIPs
iPhone DNG files can now be packed as EIPs, improving portability and workflow consistency.
For details, see Enhanced Image Package (EIP) overview.
IPTC Urgency & Color Tag Linking Toggle
A new metadata preference allows users to enable or disable the linking of IPTC Urgency with color tags. This was previously always enabled but can now be turned off, preventing Capture One from reading or writing the IPTC Urgency field.
The IPTC Urgency field is a numeric ranking system (1 to 8) that indicates the priority of an image for editorial use.
For details, see Capture One Preferences/Settings: Image tab.
New AppleScript Capabilities
New Variant Properties
- “Available crop aspect ratios” (list of text properties)
- “Crop aspect ratio” (text property)
- “Crop orientation” (enum: landscape, portrait, square)
Rotation Commands
- “Rotate Left” and “Rotate Right” commands added to rotate images in 90° increments.
Crop Aspect Ratio Management
- Create, delete, and list custom crop aspect ratios via AppleScript.
- Added the ability to read and change crop aspect ratio on a selected variant.
Create a custom crop ratio code sample:
tell current document
make new user crop aspect ratio with properties {name:"foo", ratio:1.43}
end tell
Delete a specific crop ratio code sample:
tell current document
delete user crop aspect ratio named "foo"
end tell
Delete all crop ratios code sample:
tell current document
delete user crop aspect ratios
end tell
Retrieve available crop ratios code sample:
tell current document
return name of user crop aspect ratios
end tell
Camera Support
- Nikon Coolpix P1100: file support.
For details, see Camera Models and RAW Files Supported by Capture One.

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: 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.
