    Press Ctrl-M, pull the middle of the curve downwards.

    There is no exact answer for exposure correction.

    For a simpler version, you can duplicate the background layer, then change the Layer Mode to SCREEN for under exposed foto and MULTIPLY for over exposed photos. Adjust the opacitiy for less effect.

    Thanks boss !!!

    for your info, I have this experiment to pull down the photo exposure 2 stop and done some desaturation to get better color tone. Its give more warm color. I got this hint from my friend, but the problem is, I dunno how to pull my photo exposure 2 stop under.

    You can't. Exposure is the physical process of irradiating an object with light. All photoshop can do is math.

    Maybe you might want to get your friend to elaborate clearly on what he means. What you've just described will only toss away dynamic range and cause posterization and loss of tonality if carried to the extreme.

    What kind of a digital shot in the first place would allow a 2 stop reduction and still have usable data in the highlights?

    I usually correct exposure using gamma settings or curve edit, like mentioned.

    But if all u want is to get a warmer colour tone, why not adjust the colour balance instead (add yellow/red)?
