Chapter 16. Retouching > Straight Lines

Straight Lines

Have you ever seen a carpenter “snap a chalk line” to get a straight line over an area? There are occasions when I've been grateful to know how to do something similar in Photoshop. Let's say you have an image of a woman that you need to remove from a background that contains a straight line (a wall in my case). That means that you're going to have to replace the woman with a new section of wall. For that to look realistic, the section of wall you use to replace the woman will have to perfectly line up with the sections of wall on either side of her head. When you get into this kind of situation, try this: Move your cursor until it's touching the original line (or edge of the wall, in this case). When it's perfectly touching it, Option-click (Mac) or Alt-click (Windows), as shown in Figure 16.45. Then go to the area where you want the new piece of wall to appear and click where you think it would naturally line up with the other part of the wall. Then when you drag, your two cursors will line up just right, making the line look continuous and straight, as in Figure 16.46. You can even Shift-click in two spots, and Photoshop will trace a straight line with the Clone Stamp between those two areas. Other examples of when to use this tool would be for stairs, a lamppost, or any object with straight lines that has been obstructed by another object.

Figure 16.45. On straight lines, Option-click or Alt-click when your cursor touches the line; then click in another area that also touches the line.
