Most of our forum threads are confined to the technical. The subtle design part of our profession is seldom discussed. The recent Palm Tree thread where the designer wanted to ensure that all sides of a tree were lit, suggested to me that we may not all be on the same page in terms of 'lighting sensibility'. Sensibility is defined as "the ability to appreciate and respond to complex emotional or aesthetic influences". Lighting Sensibility is our ability to create a lighting design that responds to the complex emotional and aesthetic needs of our clients. If we strive to better understand these needs, then we can do a better job of meeting them. As a beginning to the discussion, I'd say that one need is for the client to experience a nighttime ambiance in the midst of the illuminated landscape. Many installers simply light up objects without regard to the emotional or aesthetic impact of that lighting. We've all seen what a human face looks like when a flashlight is placed under the chin (monstrous). Doesn't it also make sense that lighting trees from certain unnatural angles may also elicit negative emotional responses? These may be subtle responses, even beyond conscious recognition - they may be felt as a sense of unease or distraction. On the other hand, if a tree is illuminated in a way familiar to the viewer, a way more natural, more night-like, then the likelihood of a positive response increases. Enough said on that, for more on this topic you might enjoy reading my article on the Suspension of Disbelief.
