    Default how to use curves in PS?

    hi,

    have been blindly following what some web sites teach about using curve....
    using shift the circled portion up or down a little bit depending on my pic...



    just like to find out more about using curves...
    1. what exactly does shifting diffeerent parts of the curve do?
    2. shifting the part circled in the pic above: it affects the brightness of which part of the pic?
    3. how about shifting the curve by placing the mouse over at the mid-point of the straight line? which part of the pic does it affect?
    4. how to effectively use curve in PS ?

    thanks in advance.
    Hope to learn from everyone here....

    Curves are a hard thing to master.

    sometimes u use curves to reduce contrast instead of increasing it.

    Just a tip, do not go for more than 2 points. 3 is really the max....

    Best way is to try in PS. It becomes really hard to control so as to get a "smooth" curve. A bumpy "aggressive" curve usually does not look nice unless in special cases (like you wanna do some special effects in sepia). What you are aiming for is a simple and smooth curve.
