IIQ or PNG: which should I use?

Use IIQ for adjusting exposure and white balance with maximum latitude. Use PNG for screenshots, logos, text graphics and cut-outs. Keep in mind the main drawback of PNG: large files for photographs.

IIQ to PNG for reproduction, heritage and retouching work

Phase One backs are widely used to photograph artwork, documents and museum objects, as well as for high-end product and fashion work. In those settings a PNG from the IIQ is a useful lossless working copy for people without Capture One: a conservator marking up details, a designer placing an object on a page, or a retoucher cleaning a background.

For reproduction work, be clear about what this conversion is. It develops the IIQ with the white balance stored in the file and saves 8 bits per color channel; it does not apply color targets, custom profiles or any calibrated workflow. Color-critical masters should still come from a calibrated RAW workflow, with this PNG used for reference, layout and review.

Medium-format PNGs are very large, so trim the frame to the object or detail you need before sharing it. To show a whole session quickly, IIQ to JPG produces much smaller files.

Before using the PNG as a reference copy

Compare color against the original object or a calibrated master, not memory
Label the file as a reference so it is not mistaken for the archival master
Keep the IIQ with its capture notes alongside the PNG
