  • Using Focus Stacking and Hyper Focus to Make Sharp Images

Focus stacking is a technique in which multiple images, each made at a different depth-of-field, are merged together in a software program. The resulting merged photo will be sharply focused throughout, without the variations inherent in an image with a single depth-of-field focus.

The hyperfocal distance is the closest distance at which a lens can be focused while keeping objects at infinity sharp. When the lens is focused at this distance, all objects at distances from half of the hyperfocal distance to infinity will be in focus.

Master photographers Ken Spencer and John Nixon will discuss how to use these techniques at this workshop, which is free and open to anyone interested in photography.

Topics include:

  • Selecting a focus area
  • Focusing accurately
  • Making multiple images
  • Software programs
