These words by Tom Ang on seeing as a photographer:
It’s not what you see that creates a photograph, but how you see it.
– Tom Ang
– Digital Photography – Step by Step, p.130, Dorning Kindersley, London – 2011 edition
This would seem to be the case if you are mostly interested in the “art” of photography. However if documentary photography (photographing events, subjects and scenes as they really are) is your focus then there is likely to be less freedom or scope for interpretation.
I’m finding the book quoted from above (a recent gift) to be a very useful and practical guide on photography. It is almost unbelievably densely packed with detail and information on virtually every aspect of the photographic process.
