Obama Hope Lithophane
Description
Using The Obama Hope Image, I Created A Basic Lithophane. Lithophanes Use Thinner And Thicker Areas To Create An Image. When You Hold The Lithophane Up To A Light, You Reveal The Image And Can See How Varying Thickness Creates Shadows And Specific Designs. I Used Photoshop To Put The Original Poster Image In Gray Scale, Then A Lithophane Generator To Extrude The Image (Played Around With Z Variables Until It Looked Correct When Lit From Behind). One Print Was Done At 20% Infill, Which (As You Can See) Resulted In A Plaid Jacket Effect When Held Up To The Light. If You Increase The Infill To 40-50% The Lithophane Is More Solid. You Can See From The Pictures That I Experimented With The Obama Hope Image, The Original Photo, And With Various Levels Of Extrusion And Infill. Personally, I Kinda Like The Plaid. :) I Think 3D Printing Is A Great Way To Update The Lithophane Making Process And Continue To Transform Popular Images. Here, I Wanted To Emphasize The Tactile Elements Of Visual Data - The Lights And Darks Represented By The Peaks And Valleys. Similar To How Sound Waves Allow Us To "See" Sound, I Wanted To Create A Work Where We Could Touch Light And Dark.
