How to create a blurred depth of field
Presented by: Darcy Wheeler Software covered: Lens Effects, Photoshop
Distracting elements like tree branches, street signs and cars are often unavoidable and can avert attention from the subject in focus. Typically a shallow depth of field is ideal in this situation. However, depending on the lens and distance from the subject in focus to the object behind it, this effect may not be achievable.
A handy tool to keep in mind is Topaz Lens Effects, which contains a custom depth map that allows you to add in selective bokeh. Bokeh is Japanese for “blur” and is defined by the aesthetic quality of the out of focus lighting. While most commonly noted as “Hollywood” bokeh, or a rounded orb, bokeh can also be classified as the actual out of focus area of light.
To achieve a blurred depth of field, an aperture of f/3-1.2 is ideal. However, if circumstances do not allow this, you can still create a digitally simulated background using the technology in Topaz Lens Effects. Follow this tutorial to learn how.
