Deep Focus P.2

What is the hyperfocal distance? What does the circle of confusion mean? How does a larger or smaller lens affect the hyperfocal distance?

Hyperfocal distance is everything from half that distance to infinity is acceptably sharp. This allows for the short to have the deepest possible depth of field. The circle of confusion is how out of focus a point of light can be to still be considered a sharp point of light. The hyperfocal distance is defined by the distance between the subject that matches exactly the acceptable size of the circle of confusion. The smaller the focal length, the closer the hyperfocal distance. Vice Versa, the larger the focal length, the further the hyperfocal distance. Additionally, the higher the Fstop, the closer the hyperfocal distance. the larger circle of confusion can also decrease the distance of the hyperfocal distance.
