For many years Syd Cumbus has provided a brief review of the week’s meeting to the Lancaster Guardian for their social scene column. We’re now very happy to be able to also present these round ups on the website.
The last formal meeting of the season was presented by
Christian Cable for his ‘President’s Evening’. The lecture was about the advantages and disadvantages of digital photography.
Christian started by commenting on former methods of storing images using film which was processed in a darkroom and prints or transparencies made which were safe for archival files. With digital images which are stored in a computer and are not as safe Digital images need constant back up because of the possible failure of the hard disc which has an approximate life of five years and the life of DVD’s which last about ten years. Christian advocated using the 3 – 2 – 1 rule which stated that it was best to keep three copies of each photograph with one away from the computer.
Christian followed his introduction with a series of digital photographs of subjects of particular interest to him including:-
- The seaside with images of Blackpool, Morecambe and Plymouth
- Transport showing moving traffic, London Underground stations, Trains and escalators
- The subject ‘Abandoned’ showing derelict buildings, closed shops with old fasciasStreet Art showing graffiti
- The sky with images of clouds and spectacular sunsets
- Food with photographs of peppers and pasta
- A German village in the wine growing area of the Mittel Mosel showing the landscape of vines in winter
Part two of the talk analysed the advantages of digital imaging in which images were captured by a sensor to a memory card then processed in a computer using Photoshop, but rarely printed. This was in complete contrast to film in which all images taken were usually printed and stored.
Christian commented on how digital processing was powered by integrated computer circuits. It was interesting to note recent history, in which Gordon Moore, of Intel evolved, in 1965 what has become known as Moore’s Law which states that the number of components in an integrated circuit doubles every two years and this expotential improvement has increased speed of processing, all with components which have become smaller and faster. A good example being the latest iPhone which produces superior image quality over cameras manufactured just a few years ago. As technology advances the cost of cameras have also fallen with the Canon 350D of 2005 costing almost twice as much as the newer Canon 600D of 2011.
The vote of thanks to the President for an informative and most interesting evening was given by Sally Anderson.
