Depth of Field
What is Depth of Field?• The distance from foreground to background that is
in acceptable focus.• If the camera is equipped with a zooming in/out
feature, then you can usually see the camera automatically adjusting the depth of field.
• Most of the time the digital camera focuses the depth of field for you automatically.
• Because the camera does it automatically and we cannot necessarily choose our f-stop to define our focus, we can create this image using techniques in Photoshop.
Why to Use Depth of Field?• Differential focusing is a great way of
isolating your main subject from distracting surroundings or directing the eye to a specific part of the frame.
• It adds a strong 3D feel to a photograph.
• Using this technique allows the background to not compete for attention with the main subject.
What is an f-stop?• F-stop means aperture
diameter• Reducing the aperture
diameter increases the f-number, which increases the depth of field.
• Higher the number, the more in focus ONE spot will be in the image.
• Lower the number, the more in focus the ENTIRE image will be overall.
