Vernon,
It is good for those that want to be able to open their RAW images for their specific camera and make basic adjustments -- then be able to print from the RAW file.
QU can do more than "basic adjustments".
Do not forget that QU has an image editor too so in addition to the basic raw processing, the editor can be used to do more sophisticated adjustments. In particular the Deep Focus and Tone Targeted Sharpening features are very advanced - just think of the advantages of sharpening with no halos and artefacts! All the usual features of an editor are there, some are missing like perspective correction, but for me, that is an exception where I would go to an external editor with a tiff made in QU.
We'd be interested to know what other adjustments you may want to do?
