51 chapter 4 What is on the Screen? Top Page Glossary Contents Index Here are some hints for editing curves: •Curve handles are drawn on a white background as a red dot to signify that they are editable. When the cursor is over the handle, it changes to a crosshair. •Curve end points can be selected and dragged to any point in the curve but cannot be deleted. •Up to 15 points can be added to a curve by clicking anywhere in the curve box. •If you drag a point outside of a curve box, it will be deleted from the curve and a new curve will form with the remaining points. •The x and y axes on the curve chart represent the input image color and output image color. When you add a handle to the curve and drag that handle toward the white areas, the preview image tones are adjusted to reflect the change. •More than one handle cannot be positioned on a vertical line but more than one handle can be positioned on a horizontal line so you can have several handles on a horizontal line.
