Convert RAW to IIQ

Understanding RAW and IIQ file formats

RAW files are unprocessed image files captured directly from a camera's sensor. They contain all the data recorded at the time of shooting, offering maximum flexibility for post-processing. RAW is a generic term and can refer to various proprietary formats from different camera manufacturers.

IIQ is the proprietary RAW image format used by Phase One digital cameras and backs. IIQ files store high-quality, uncompressed or compressed image data, and are specifically designed for use with Phase One's Capture One software, providing advanced editing capabilities and optimal image quality.

Why convert RAW to IIQ?

Converting a generic RAW file to the IIQ format may be necessary if you want to utilize Phase One's advanced image processing tools or maintain compatibility with their workflow. However, this conversion is uncommon, as IIQ is typically created directly by Phase One cameras. Converting other RAW formats to IIQ is not widely supported and may result in loss of metadata or image quality.

How to convert RAW to IIQ

There is no mainstream software that directly converts generic RAW files (such as .CR2, .NEF, .ARW) to the IIQ format, as IIQ is a proprietary format intended for Phase One hardware. Capture One, the official software from Phase One, can import and edit various RAW files, but it does not export or save images in the IIQ format unless the file originated from a Phase One camera.

If you need to work with RAW files in Capture One, simply File → Import Images and select your RAW files. You can then edit and export them in other formats such as TIFF or JPEG, but not IIQ.

Best software for working with RAW and IIQ files

• Capture One – Best for editing and managing both IIQ and other RAW files. Supports a wide range of cameras and offers professional-grade tools.
• Adobe Lightroom – Excellent for editing most RAW formats, but does not support exporting to IIQ.
• Adobe Photoshop – Can open and edit RAW files, but does not support IIQ export.

For conversion between RAW formats, consider using Adobe DNG Converter to convert proprietary RAW files to the open DNG format, but note that IIQ is not a supported output.

Summary

Direct conversion from generic RAW files to IIQ is not supported by any mainstream software due to the proprietary nature of the IIQ format. For best results, use Capture One to edit and manage your RAW files, and export them in widely supported formats like TIFF or JPEG.
