I am thinking about the lift/gamma/gain, as compared to the current “color balance”, which is kind of poor.
The libraw quality is out of question (it is good), what I mean is that the options for changing stuff are not intuitive at all and many interact with each other in ways I find difficult to understand.
What I would rather have is a “full-raw” histogram, for each one of the color channels, good colour control tools that are actually applied at the raw level, so I can do my edit, which is typically to recover highlights and shadows, then adjust colours. I think most people have almost 100% of that need at raw level. As of now, the “good” part of the processing is after the raw = same as doing it in 16 bits later in the main picture edit tool = useless to some extent.
Do not get me wrong! Love the program. It is only just a few steps from being fucking awesome in all I need (outside of gimp for retouching, the clone tool included in the edition tool is just not good enough).
