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
