"I am touched by the reverence with which Mark's eyes approach the world before him, the tenderness with which he sees subtle simple beauty that is nearly invisible to, and most often ignored by, passersby.

"He discovers almost hidden secrets, things that existed at a particular moment, fleetingly and only for him. The meaning too was apparent only for him and the intensity of his feeling. Few ever observe and make such minute and meaningful connections between light and ever so transitory revelations. Mark Citret walks lightly over this earth but sees so much."

—Ruth Bernhard, from the introduction to Along the Way
