The most used type of modification is to create a \textit{S curve}. There can be a lot of shapes that use the S curve; the simplest is to create a control point in the shadows, one in the midtones (anchors) and one in the highlights. Moving the highlight point upwards and the shadow point downwards increases the contrast, making the image sharper and improving the color rendering. With the type of \textit{linear} curve you can make hard adjustments, similar to the result of the use of \textit{Color 3 Way}, even if this acts on the color wheel (Hue) while the curves act on individual RGB channels.
-The \textit{Polynomial} and \textit{BÃ©zier} types introduce \textit{control handles} that allow for more sophisticated and smoother adjustments. The quality of the result is much better, but they require more experience for their optimal use. Extending the handles away from the control point increases the \textit{radius} of the curve at that point. By varying the angle of the handles we change the \textit{tangent} and thus the curvature of the curve below. The difference between Polynomial and BÃ©zier lies in the underlying mathematics, but for practical purposes the use is similar.

The quality of the result is much better, but they require more experience for their optimal use. By varying the angle of the handles we change the \textit{tangent} and thus the slope of the curve below. Unlike true Bezier curves, there is no effect in extending the handles: there is no change in the radius of the curve. The difference between Polynomial and BÃ©zier lies in the underlying mathematics, but for practical purposes the use is similar. By default BÃ©zier starts with a slight S-curve, as opposed to Polynomial.
Some examples of the use of curves to demonstrate the variety of possible interventions (figure~\ref{fig:ex-bezier}):
