Adobe Photoshop CS6 Top 100 Simplified Tips and Tricks by Lynette Kent

INCREASE DEPTH OF FIELD with the Auto Blend tool
(continued)
To create the best blend for extending the depth of
field of the final image, you should use a tripod and
use the manual focus of the camera. With the full
image in the viewfinder or on the camera’s LCD,
manually focus on the area closest to the camera and
take the first shot. Then change only the focus point
to see the next area over in sharp focus. Continue
taking photos until all the areas are in focus in at
least one shot.
The Auto-Blend Layers command works only with
RGB or Grayscale images and does not work with
Smart Object layers or Background layers. And
although the Auto-Blend dialog box does have an
option for blending multiple images into a panorama,
the Photomerge command generally produces better
photo blends for panoramas.
You can use as many photos as required to capture
each area of the scene in sharp focus.
