When designing exhibition lighting, we must remember that the observer’s point of view is ever-changing, moving around the space and creating infinite possibilities. Our lighting design should embrace these varying perspectives, ensuring a comfortable and engaging experience for every viewer. For three-dimensional objects, lighting is not just functional—it’s essential to reveal their unique characteristics and captivating viewers.

The first element to consider is the object's location. Is it on a stand, near a surface with a specific finish that could influence its appearance? What is its background? Can it be viewed from all sides, or only from limited angles? Understanding these factors helps determine the optimal placement of light sources. After this initial study, we can assess potential glare or reflections caused by the light sources. A thorough analysis of the location and the use of anti-glare accessories can reduce glare, concealing the light source from the observer's eye.

Imagine standing before a beautifully lit sculpture. The primary light source tilted at about 30° away from the object, bathes it in a soft, even glow. This careful positioning illuminates the sculpture effectively while avoiding direct glare or reflections on the display case. As you move around, the interplay of light and shadow brings out the sculpture’s intricate details and textures, enhancing its shape and character. High contrast can create dramatic effects, making the object pop against its background. A contrast ratio of 3:1 typically makes the object stand out, while a ratio of 10:1 can add emphasis without causing discomfort.

Now, consider the properties of the statue or object being illuminated. Materials, colours, finishes, and textures all react differently when lit. Accent lighting generates a different effect than diffuse lighting, and the angle of the light can significantly enhance texture and shape. Similarly, different colours and materials respond uniquely to various light colour temperatures. It is crucial to use the right correlated colour temperature (CCT), high colour rendering index (CRI) LED chips, or light sources that enhance specific wavelengths if needed to highlight the object's colours. Gels and filters applied to the light source can also be very handy in adjusting the design.

Utilizing two or more light sources can help highlight the multiple characteristics of an object. A primary, diffused light source provides a general bright wash to make the object stand out from the background, while accent lights intensify the shapes, movements, and details of the sculpture. This combination can bring the object to life, emphasizing its depth and texture in a captivating manner. The strategic use of lighting transforms a static sculpture into a dynamic piece of art, engaging viewers from every angle.

Daylight adds another layer of complexity and beauty to the design process. While it can have damaging effects on colours and sensitive materials, it can also create an ever-changing installation when used with materials like marble, clay, and glass. Imagine how the shifting sunlight can play across a sculpture, continually revealing new facets and details.
