IIQ to HDR conversion is the process of transforming a Phase One RAW image file (with the .iiq extension) into an HDR-compatible image format that preserves expanded dynamic range and tone-mapping information. This conversion decodes the camera's RAW sensor data, applies linearization and exposure/range adjustments, and exports an HDR-ready file suitable for high-dynamic-range workflows, display, or further editing.

IIQ files typically have the MIME type image/x-raw-iiq and are raw files that contain sensor data from high-end cameras. HDR files often use formats such as Radiance (.hdr) or OpenEXR with MIME types like image/vnd.radiance and are used for storing high dynamic range images. Codecs and software supporting HDR focus on merging multiple exposures or tone mapping for enhanced image presentation.
The HDR (.HDR) format is commonly used for image. Understanding its characteristics can be helpful when converting to or from other formats like IIQ.
While specific technical details aren't available here, HDR files generally serve the purpose of storing image effectively within their domain.

IIQ is a proprietary raw image format used primarily by Phase One cameras, storing unprocessed sensor data for maximum flexibility in editing. HDR files, on the other hand, store high dynamic range images that combine multiple exposures to capture greater detail in shadows and highlights. While IIQ focuses on raw data capture, HDR concentrates on enhancing visual dynamic range for display and editing purposes.
Keep original IIQ files and convert from the RAW master to preserve full sensor data; export HDR as 32-bit float EXR or linear 32-bit TIFF for best dynamic range retention.
Optimal file sizes: expect HDR master files (32-bit EXR/TIFF) to be 3–10x larger than the original IIQ depending on bit depth and channels; plan storage accordingly.
Preserve quality by disabling aggressive camera-side processing (in-camera sharpening/noise reduction) before conversion and apply tone mapping after exporting a linear HDR file.
For batch conversion, use a dedicated RAW processing tool or command-line pipeline (e.g., Phase One Capture One, RawTherapee, or dcraw + OpenEXR tools) to automate consistent settings across images.
