About This Idea

Control depth of field in photography and videography to create professional-looking images with sharp subjects and blurred backgrounds. Depth of field (DOF) is the range of distance that appears sharp, controlled by aperture, focal length, and distance. Mastering DOF helps you guide viewers' attention and create cinematic visuals.

How to Get Started

UNDERSTANDING DEPTH OF FIELD (1 hour)
  1. Learn the basics: Shallow DOF (blurred background, sharp subject) vs deep DOF (everything sharp)
  2. Understand aperture: Lower f-number (f/1.4, f/2.8) = shallower DOF, higher (f/8, f/16) = deeper DOF
  3. Know the factors: Aperture, focal length, distance to subject - all affect depth of field
  4. Watch 'Depth of Field Explained' by Peter McKinnon (youtube.com/@petermckinnon) - visual examples
PRACTICAL TESTING (1-2 hours)
  1. Set up test shots: Same subject, change only aperture - see how background blur changes
  2. Try different focal lengths: Wide angle (more in focus) vs telephoto (less in focus)
  3. Experiment with distance: Closer to subject = shallower DOF, further = deeper DOF
  4. Practice portrait mode: On phones, portrait mode simulates shallow DOF - compare to real camera
  5. REAL-WORLD APPLICATION (1 hour):
  6. Portrait photography: Use shallow DOF (f/2.8 or lower) to blur background, make subject pop
  7. Landscape photography: Use deep DOF (f/8 or higher) to keep everything sharp from foreground to background
  8. Creative control: Use DOF to guide viewer's eye - what should be sharp? What can be blurred?
  9. Practice in manual mode: Set aperture yourself, see immediate results, learn the relationship
