Re: Exam with no answers FWIW

[James Schenken <jds@xxxxxxxxxxxxxxx>]

01 - Most SLRS or DSLRs use focal plane shutters.

17 - 'tail flash' occurs when the majority of the exposure happens before the flash goes off.  So to simulate this effect by using a relatively slow shutter speed and open flash manually triggered.

18 - this pattern could be made by a tiny light suspended on a string and swung as on a pendulum with the camera shutter speed being quite slow in a darkened room.  

28 - this is an example if stress visualization in the plastic by using polarized light.

29 - Any large first surface reflector can be used to polarize light.  Just reflect the light at an angle from the reflector on to the desired object.

30 - a lens from a simple, no-prescription pair of sunglasses will do.  A piece of cellophane will do as well.

Cheers,
James
