In July, Dan Evans gave a presentation on ‘Lens Lore – using the lens for best creative effect’. Although trained as a botanist, Dan changed careers early in life to become a professional photographer, co-founding a photographic training company (Focal Point Photography) in 1981 and later becoming the in-house photographer for the global company, DRS Data Services. He is now freelance, specialising in fashion and design, portraiture, weddings, interview support and various other commercial work including on-location training courses.

Dan opened his presentation by reviewing the characteristics of telephoto and wide angle lenses, with particular reference to magnification and its effects on depth of field and field of view, commenting that modern digital lenses are now so good that aesthetic qualities predominate when taking photographs, rather than technical issues as previously. Any spurious technical deficiencies can be corrected through post-production software.

Dan stated his normal preference is landscape photography, using ambient light and shooting in RAW at ISO 1600, which is generally noise-free on modern sensors. He then contrasted the full frame sensors found on high-end cameras to the smaller APS-C sensor format of more popular, cheaper models, commenting on the latter’s weight advantage. The high quality of modern sensors means that prints up to A3 size are now virtually indistinguishable between the two formats. He then demonstrated the extraordinary Canon rectilinear fish-eye lens, in which all distortion characteristics are eliminated, and concluded by showing a wide range of his commercial and personal work, accompanied by tips and comments on how he achieved his photographic effects. Overall, this was an excellent, frank and inter-active presentation by an extremely knowledgeable photographer, that was greatly appreciated by his audience.
