There is no doubt about it, the colours in C1 are on a different planet for accuracy compared to adobe when working with RAW files. Especially with skin tones where it almost makes me cry to see the difference! I've been using ACR practically since it was first released, I use DNG Profile Editor, I have a Gretag (or whatever they call it these days) chart. I can't get skin tones to look anywhere near as easy and accurate as C1 does. Heck, even the WB tool is far more accurate in C1. The highlights recovery is also far better implemented (works globally not just on contrast). Detail is better as is (especially) the colour noise reduction tool.
But. The ACR engine and especially the tools such as the Local Adjustment Tool and Targeted Adjustment Tool are far better. Heck just being able to set the black point easily without having to describe a custom curve or apply changes to just one setting to multiple images is far easier in ACR. I'm a wedding shooter and the ability to dodge and burn in a RAW converter is too much of an advantage to give up after all these years of waiting for it!
Does anyone have any idea how I can get C1 colour in ACR? Please pretty please? Either that or I spend more time trying to get to know C1 (huge list of questions if that's what I'm doing ) and save to 16 bit TIFF, then open in ACR for dodge and burn (yeuch, will add hours to my workflow ).
