I hold my hand between the lamp and the desk’s surface. The darkest place, where my hand blocks the direct rays of electric light, is the umbra – latin for shadow. The penumbra (almost, nearly, shadow) is the partial occlusion of light, where the darkness is less severe, seen in this case, emanating briefly from the edges of the umbra, from my dark finger tips. The antumbra is something that cannot be described.”</span></p> <p>–<span class="quote-source"><a href="http://gorse.ie/portfolio/on-the-absence-of-light/">Hugh Fulham-McQuillan</a> <br /></span></p> <!-- tumblr url: [https://agalmic.org/post/146412652882](https://agalmic.org/post/146412652882)-->
