|Tumbledown Window - Mojave, California|
Note the lines that lead the viewer from the top corners to the window.
Photographs are not the capturing of objects, but the capturing of light (highlights and shadows) and color (if not black-and-white). Highlight, shadow and color make up the shapes within each image. Those shapes often have natural lines--some are straight lines and some are curved lines.
The first principal of Leading Lines is that you want to avoid lines coming from the edge of the frame. Often lines that extend to the edge of the frame will lead the viewer right out of the image. Lines that come from the corners are fine because, for whatever reason, these lines tend to lead the viewer into the frame. So it is much better to put the lines into the corners of an image than along the edge.
|Torn Veiled View - Tehachapi, California|
Notice that the window creates natural lines from the top and bottom left that lead to the tear in the window screen.
The third principal of Leading Lines is that they need to lead to something. If there is no punchline, the viewer will be guided to boredom. Leading Lines that don't lead are not Leading Lines. So have something (typically, the main point of the photograph) at the end of the lines as a surprise for the viewer.
Carefully and thoughtfully compose your photographs to use the natural elements that are already there to guide the viewer to what you want them to see. This will keep the viewer's attention longer and give them the impression that what they are viewing is worthwhile.
It is important to make meaningful images. If the viewer cannot find the meaning within a short look, they will move on and the photograph is pointless. Don't let that happen. Use Leading Lines to take the viewer's eyes to where you want them to go.
