  edges.

• Extended depth of field
  Whether it's the extreme
  close-up, the microbial world, or simply low-light conditions, there are
  times when the depth of field you can capture with your camera is extremely
  shallow. Now, you can shoot the scene with a series of focal points, and use
  the enhanced Auto-Blend Layers feature to automatically create a new, single
  image with a depth of field encompassing the entire series. You can even
  colour-correct the images at the same time, automatically. This feature
  provides breathtaking enhancement of any scene where lighting and depth of
  field are in short supply.
