IIQ to JPG: viewing Phase One captures without Capture One

IIQ is the RAW format of Phase One's medium-format digital backs, from the P-series, such as the P40+ and P45+, to the IQ series, and of the XF camera system built around them. Phase One's aerial and industrial cameras use it too. Capture One, Phase One's own software, is the usual way to open these files, so a JPG is what you need when the person looking at the pictures does not have it.

Resolution varies widely across the range, from under 20 megapixels on the earliest P-series backs to 100 and 150 megapixels on the newest IQ models, and the largest of those files can be too big for the converter to accept; export those from Capture One instead. Smaller IIQ S files are the easiest to upload. Without a plan, each file can be up to 20 MB; Premium allows 50 MB and Pro 120 MB.

For a session, Premium's batch mode converts up to 60 files in one go (200 on Pro), which suits a quick contact set for an art director. Lower the quality a little for those previews, since a full-resolution JPG of a medium-format frame is large. For retouching, IIQ to PNG gives a lossless file, and you can bundle the selected frames into one PDF for review.
