CaptureOne 6.4.5 32 bit - cannot view IIQ files

Postby Rosco88 » Mon Sep 28, 2015 9:55 pm

Evening All,

I have been to an open event today and used some of the new PhaseOne cameras, Upon returning home I have downloaded 6.4.5 (only 32 bit program i could find) and it is not recognizing the files on the card.

I can see the files in Windows Explorer, but they wont open or be viewed in any program.

Does anybody have any ideas?

Which camera?

It is supported by that version of Capture One? ... meras.aspx?

Just because IIQ is a supported file format, it doesn't mean that an old version of Capture One will read an IIQ file from a newer camera.

This is an absolutely fundamental "must know" aspect of digital photography, Ross - it's the specific camera model that's relevant to whether a file from it will open in a given version of a converter's software, not the file format.

Old software can't be expected to understand files from new cameras.

You are apparently limited to 32-bits software, which effectively limits your options as Capture One is only 64-bits since CO7.

If you ever enter the 64-bits area, please be aware that Capture One when running in the so-called DB mode, is free of charge and let you evaluate the IIQ files unlimited of any trial period.
