levels or curves -- photoshop

If you just want to adjust the black and white points you might say that Levels and Curves do about the same thing. However, the real difference is that Levels gives us only three points to work with - a black point, a white point and a single midtones slider. Curves, on the other hand, gives us as much control as we want. We can add up to 16 individual points along the curve for pinpoint accuracy when adjusting brightness values!

Here's an excellent web page (link below) that does a nice job of explaining the difference between Levels and Curves.
