In this video tutorial we look at lens focal length and using selective focus to add visual impact to your images. Various examples of different lenses and settings are given for comparison.

The video then goes on to show you how to create a similar effect within Photoshop, recreating depth of field after using a narrow aperture when shooting.

Key Points for Wide Angle Lenses

• It isn't easy to drop backgrounds out of focus, even at the widest F stop.
• This is not a flattering lens for most portraits, as it can cause unwanted distortion.

Key Points for Longer Focal Length Lenses

• Lenses with a focal length of 70-200mm are ideal for selective focus.
• They also compress elements in the frame and can give a more flattering portrait.
• Be careful of focusing at wide apertures, as the margin for error is small.
