DPP shows realtime changes in histogram when adjusting curves. u can select to view as a single RGB curve or view all three R, G, B curves overlap all over each other. u can also adjust either as a whole curve or adjust each individual R, G, B curve.

Exposure affects only the amount of light hitting the image sensor, and thereby corresponds to "brightness".

Likewise, I quoted a strong statement to make my post more attention grabbing.
Yah I am slowly understaning Photoshop and its tools.
And I must say the many comments by all you guys have helped.

Sorry if this is too basic a question, but, er... what is DPP?

I just came upon this..
i would still recommend curves and levels over B/C .. simple reason being that you have more control over which part of the spectrum you are affecting..
But if you have ALREADY done a B/C and applied it.. don't recommend going over again.. every edit washes out pixel info..
that's why it's good to have back-up... OR to do this stuff in RAw first! (or use adjustment layers )

Thanks for the advice.

So many things to learn and understand. Fun but also tiring.
