Photography I / Lenses, Field of View and Depth of Field
Practice question · Put in order

Arrange the steps of pre-setting a lens for street work by the hyperfocal method in the order they are carried out.

Hints
  1. The requirement comes before the aperture that satisfies it.
  2. The last check is the one that decides whether the whole scheme is workable in the light you have.
Show the answer
  1. Decide the nearest distance that must come out sharp
  2. Double it, since the near limit lies at half the hyperfocal distance
  3. Find the aperture whose hyperfocal distance for this lens matches that figure
  4. Set the focus ring to that hyperfocal distance and leave it there
  5. Check that the shutter speed still available at that aperture is usable
Why

The last step is where the method usually fails. A near limit of one metre on a 35 mm lens demands a very small aperture, and in dull light the shutter speed that goes with it is too long to hold, so the honest answer is often to accept a nearer limit of two metres rather than to pretend the exposure works.
