Pinhole Vs Zone Plate

  copyright 2000-2003 Zernike Au

 

The left hand side images are pinhole images.

The halo effect of a zone plate is obvious when the light condition is in high contrast


 

The light bulb is only 15W, exposure time for the pinhole is

about 45 minutes and that for the zone plate is 18 minutes.

The halo effect of the zone plate is not strong due to

dim light conditions and long exposure time.


The whole scene is softened by zone plate which

enriches the artistic atmosphere of the image. 


 

Camera: Zero 2000 pinhole and zone plate camera w/tripod

Zone Plate: 25mm w/5 clear zones, f/47.6
