DSLR photographers love the out of focus areas of their photographs, it’s one way to differentiate their pictures from entry-level cameras and smartphones where exaggerated out of focus areas are hard to achieve. Bokeh is the term used to describe the quality and characteristics of these out of focus areas and is most visible in blurred highlights.
The amount of bokeh increases when your image has a shallow depth of field or more out-of-focus area. So controlling the amount of bokeh in your images depends on increasing the blurred areas. Below are a few ways to add blur to your images by decreasing depth of field which adds bokeh to your images.
1. Use a ‘fast’ lens – this refers to those with a large maximum aperture, we recommend the EF 85mm f/1.8 USM or the EF 50mm f/1.8 STM
2. Shoot with a large aperture – using Aperture priority (Av) or Manual (M) Mode on your camera, select a wide aperture (small f/number) to decrease the depth of field and increase out of focus drop-off from your in-focus subject.
3. Increasing the distance between your subject and the background will further blur the background.
4. Get in close – minimising the distance between you and the subject will increase the amount the background is out of focus.
5. Use longer focal lengths to increase the amount of out of focus area in your photos. If you have a zoom lens, zoom to maximum focal length. Lenses with a focal length of 200mm or more will produce even greater blurred areas.
