--------------------------------------------------------------------------------

I have just recently noticed a colour shift between a file processed as Quick Proof and as a jpeg. When opened in PS, the jpeg is an almost identical match to C1, whereas the QP file looks flat and lifeless.
They are both processed one after the other.
TIA

"Flat & lifeless" sounds like a colorspace mismatch, e.g., an Adobe RGB file being viewed as sRGB or in a non-color-managed environment.

Thanks Nill, I will look at that .
Many thanks for replying.

A Quick Proof is not unlike BreezeBrowser extracting the embedded JPEG in a RAW file. Your JPEG conversion is just that, a conversion from the RAW. Depending upon your capture settings can look very different. Additionally, Nils' suggestion is a good one.

yeah, that'll happen. QP jpg's exist so that Phase can say that you can process JPG's really quickly, although compared to other programs, it really ain't all that fast! If you want better quality JPG's you need to process them on Quality High.
