I'd also suggest using a custom made profile for your camera. I used ColorEyes 20-20 and am getting very accurate color reproduction. The one thing I want from this program is a better file browser. The single row or column of thumbnails doesn't show enough thumbs, IMO. I also wish the thumbs would update their color with the raw file.
I only can agree with the praise for this application. Best RAW converter I ever used, at least for Canon 5d files (for Fuji S3/ S5 files I prefer Lightroom). The output is looking natural and great. However I almost exclusively work with my own modified presets. I hav ebuilt a dozen or so for different looks - and yes I also changed the input curve - the default curves are generally too steep on the bright side.
However I am not understanding how to get a specific camera profile for RAW developer and at what stage to use it - sorry for my ignorance.
As for the file browser, I never use it. I use the OS-X finder in the thumbnail mode and just drag and drop it on the Raw Developer thumb in the dock, or I do the same thing from Lightroom. Works every time and I don't have to get around RD's limitations.
