What is the difference between Exposure or Brightness in the PS plugin for RAW files?

Thanks

Brightness adjusts mid tone brightness without affecting the ends of the tonal range - watch your 'live' histogram in PSCS as you adjust it and you'll see just what happens.

Yup, this is one of the big reasons I like PS CS raw.
The Exposure, Brightness, and Shadow sliders make it easy to take full advantage of the entire Dynamic Range of a raw file. No other software I've used, including C1 Pro, offers such control IMHO.

Have you tried DPP? It has a special "Dynamic Range Adjust" control, which allows you to select exactly how to map the 12-bit per channel linear RAW data range to the output range.

that is effectively what PS RAW does but with DPP1.5 you do have more control, as long as you know what you are doing. PS gives a more user friendly approach.

I have run a few shots through both all based on 2 stop bracketed exposures. DPP does slightly better on the overexposed shots, PS slightly better on the underexposed ones.

Yeah, I tried DPP1.1 and DPP1.5, but they both suffer from the demosaic and purple fringing bug.
I didnt find the Dynamic Range Adjust as intuitive as the method found in Adobe Camera Raw either.
