What are the benefits of professional engineering photography?

Perception is nine tenths of reality, your clients may be engineers, but they still react to sophisticated marketing.           Unique, sensory, resonant photographs stand out against your competitions forgettable 'home made' imagery.           Theodore Levitt says it best in his book Industrial Purchasing Behaviour: a study of communication effects. A carefully controlled study showed that;           "....technically sophisticated technical personnel seem to be influenced by the sellers reputation to a point that is unexpectedly higher than the influence of that reputation on such technically less sophisticated  personel as purchasing agents.... In.....trying to sell such products to technically trained personel it may not be wise to rely so unevenly on the products  inherent virtues and on making strong technical presentations."           Engineers are people too.
