Convert DNG to IIQ

Understanding DNG and IIQ file formats

DNG (Digital Negative) is an open, lossless raw image format developed by Adobe. It is widely used for storing unprocessed image data from digital cameras, ensuring compatibility and long-term archiving. IIQ is a proprietary raw image format used by Phase One digital cameras. IIQ files retain all the image data captured by the camera sensor, allowing for extensive post-processing and high image quality.

Why convert DNG to IIQ?

Converting DNG to IIQ is uncommon, as IIQ is a camera-specific format. However, some photographers may wish to convert DNG files to IIQ for compatibility with Phase One software or workflows that require IIQ files. It is important to note that most software does not natively support exporting to IIQ, as it is designed for Phase One camera outputs.

Best software for DNG to IIQ conversion

Currently, there is no mainstream software or online converter that supports direct conversion from DNG to IIQ. Capture One, the official Phase One software, can import DNG files for editing but does not export or save images in the IIQ format. IIQ files are typically created only by Phase One cameras at the time of capture.

Alternative workflow

If you need to work with DNG files in a Phase One environment, the best approach is to use Capture One to import and edit your DNG files. You can then export the edited images in other formats such as TIFF or JPEG, but not IIQ. The menu path is: File → Import Images to bring in DNG files, and File → Export → Variants to save in supported formats.

Summary

Direct conversion from DNG to IIQ is not supported by any known software due to the proprietary nature of the IIQ format. For editing DNG files in a Phase One workflow, use Capture One and export to widely supported formats.
