In my last blog, I talked about leading lines. This blog let us find diagonal lines.
Diagonal lines generally work well to draw the eye of an image’s viewer through the photograph. They create points of interest as they intersect with other lines and often give images depth by suggesting perspective.
Different studies have been done into how people view images and many of them say that a natural way into an image is by travelling left to right and so a diagonal line starting at the bottom left and moving to the top right of an image can be quite useful and natural.

Of course, you wouldn’t want to split your image into two with a harsh line from corner to corner – rather look for patterns and curves between shapes that might do this naturally.
Also rather than making a line go from the very corner to the opposite corner it’s often good to make them off centre and go to either side of corners.
