Imagine holding an apple out in front of your face. What is depth? It’s a measure of the three dimensionality of things. Let the rest get a little fuzzy so the sharp part stands out.
Most of the time, only one part of your images should be truly sharp. You might not notice it, but everything else in your peripheral vision appears a little more hazy. When we focus our eyes, we do something similar. I should also mention that it’s simply harder to draw attention to things that don’t stand out on their own. The effect is akin to bringing your friend into the studio and placing him or her in front of a solid colored background. Portraits, as we have just discussed, look a lot better when the background is somewhat out of focus. Backgrounds tend to get in the way, and they will distract your viewer from the point you are trying to make. There are a lot of situations where you don’t really want the entire image to be in focus.

With that explained, here's how to use focus to improve your images: Don’t always put everything in focus The small depth of field makes your friend’s face stand out from the background. You can focus on the eyes alone while the background gets completely blurred out. That’s one reason why F4 is such a good aperture for taking portraits. You can use depth of field to emphasize certain parts of an image. At F22, the depth of field (or focus range) is much larger than at F4. In terms of actual camera settings, larger f-numbers correspond to smaller apertures. This photo uses close focus to draw emphasis to the soccer ball. Smaller holes do a better job of focusing light than larger holes. The size of the hole the light travels through (the aperture) determines how focused those rays are once they hit the sensor.
In order for a camera to create a focused image, it takes light and runs it through a lens, concentrating the rays on the image sensor inside. Before we get to the tips themselves, I want to discuss the mechanics of focus itself.
