Foundation Concepts - Understanding F-Stop and Diffraction


"Diffraction" by Craig Tanner

Posted: December 21st, 2009 @ 5:49am


In this Foundation Concept video Craig looks at the optical aberration of diffraction and how it relates to aperture and f-stop and discusses the following :
 
- a lay person’s definition of diffraction
 
- what is an f-stop
 
- a lens resolution chart showing the sharpness and contrast at different apertures
 
- what are the possible implications of the competing ideas of diffraction and stopping down to get greater depth of field
 
- link to technical definition and description of diffraction
