Selective focusing with a wide aperture can add a lot of creativity to your images. You are telling the viewer where you want the focus of the image to be, and the meaning and story changes depending on what is in focus. Using a telephoto lens can compress your background even more, decreasing the depth of fi eld and making the background or foreground even blurrier. But take into consideration that just because your background or foreground is blurry, it doesn’t mean you can’t show detail in those areas (Figure 8.1).

A very wide aperture was used in this image to create a blurred background; the man in the background is still fully visible even though the focus is on the woman.

If you want the entire image to be in focus, you would use a smaller aperture. Images with great depth of fi eld, such as a landscape or an image with a lot of detail, direct the viewer to look at the entire scene (Figure 8.2).

In order to capture all the details in this image, I used a small aperture so that the majority of the scene was in focus.
