DIG Thames Valley Centre - Our Event on 18 May 2014

20 May 2014

SIG: Digital Imaging

Attendees at the Thames Valley DIG event on Sunday were given an excellent presentation by Dr Tony Kaye, who gave us a good understanding on what affects camera image quality when taking into account the combined effects of the number of capture pixels, lens aberrations, diffraction effects, and the presence of anti-aliasing (or low pass) filters. Tony also discussed image resolution requirements given that a person viewing a print should be using an appropriate viewing distance based on image size. I think all of us had our brains stretched with the technical depth of the presentation, but the many comparison images illustrated the theories very well indeed. As chairman of the Image Science Group and an enthusuastic photographer, Tony was well qualified to talk about this subject matter, and attendees raised many questions.

The afternoon was taken up with our annual PDI competition judged by Micki Aston with her usual entertaining and informative approach to the task. For the second year in a row, this was won by Tony Mearman. We now break for the summer.
