Directional light is known to produce high contrasts and a marked modelling effect. The best way in which to view three-dimensional objects would be to have directional lighting from at least two directions.\u003C/p\u003E\n\u003Cp\u003E\u003Cstrong\u003EDisplay lighting\u003C/strong\u003E\u003C/p\u003E\n\u003Cp\u003EWhen light from other directions is added, this then reveals the contours of the object on display. An example of this is seen in backlighting, when a silhouette effect is achieved against a bright background. Moreover, lighting from below (up-lighting) causes a very dramatic effect.\u003C/p\u003E\n\u003Cp\u003E\u00A0\u003C/p\u003E\n\u003Cp\u003E\u003Cfigure role=\u0022group\u0022 class=\u0022caption caption-img align-center\u0022\u003E\n\u003Cimg alt=\u0022Illustration of up lighting\u0022 data-entity-type=\u0022file\u0022 data-entity-uuid=\u0022e79bb349-5788-4a30-ba31-290addf2a6da\u0022 src=\u0022/cms/drupal8-magnetgroup/sites/default/files/inline-images/Uplighting.jpg\u0022 /\u003E\n\u003Cfigcaption\u003E\u003Cem\u003EIllustration of Up-lighting\u003C/em\u003E\u003C/figcaption\u003E\n\u003C/figure\u003E\n\u003C/p\u003E\n\u003Cp\u003E\u00A0\u003C/p\u003E\n\u003Cp\u003E\u003Cstrong\u003EWhat is diffuse light?\u003C/strong\u003E\u003C/p\u003E\n\u003Cp\u003ELight reaching an object from multiple directions is known as diffuse light, and this produces hardly any shadow. As a result, the modelling effects are less pronounced and could even be absent with completely diffuse lighting.
