Bokeh is the small round circles of blurred like or objects in the background of photographs. You mainly see this with portraits or photos where the subject is closer to the camera than in other shots. Now when you go to shot bokeh you will want to have your camera in manual mode so you can change the f-stops and determine the aperture. There are many ways to achieve bokeh. One is to change the distance between the subject of the photo and the camera. The further away your subject is from the background you want the better. You want a shallow depth of field for your photo. By focusing on your subject and having the background blurry, highlights that are not seen will come through on your camera. When taking the photo you want a faster f-stop. So f/2 f/1.8 f/1.4 are ideal for this. You'll also want to shot while the sun is out and is a little lower then at its peak. So when it drops behind the trees.
Heres six steps to achieve bokeh. Step one: Use a large aperture. It the lens that captures the bokeh not the camera. Set your lens to the maximum aperture or lowest aperture possible. Step two: Minimize the distance between yourself and the subject. Stand closer to your subject, the blurrier the background the better. Step three: Increase the distance between your subject and the background. Remember depth of field. Step four: Use longer focal lengths, this focus more in onto your subject and decrease depth of field.Step five: Use a long lens. It will increase depth of field but use one with good optics. Step six: Use a fast lens. Your faster lens has a lower aperture so you'll have a better chance at getting bokeh.
