My Photographs

I am now using 500px to host my photographs at

Pinholes and Zone Plates

The Pinhole Optics Designer software now supports building Photon Sieves in addition to Pinholes, Zone Plates and Pinhole Sieves.

An in-depth explanation of how I produce pinholes, zone plates, etc. can be found on  the Zone Plates page.


The "Views of Lansdowne" collection of photographs can now be viewed online.
