Floodlights aimed upwards make the tree crown appear three-dimensional. Two floodlights from the front, yet to the side, illuminate the crown evenly as a voluminous mass, while floodlights mounted at the side add greater emphasis to the three-dimensionality. Floodlights arranged around three sides illuminate the crown evenly from all sides and reduce the three-dimensionality of the tree form. Floodlights in the background create back-lighting and make the tree crown into a silhouette Uplights at the trunk accentuate the trunk as a linear feature and visually connect the crown to the ground. Depending on the season, light from above will either emphasise the contour of the crown or accentuate the shadows of the branch structure on the ground.
