The size of shadow an object casts, is directly related to the position of a light source. the higher up a light source is in relation to the object, the shorter the shadow will be. Shadows cast by objects lit by the sun in the morning or evening are long, because the sun is low in the sky. At mid-day, the shadow is shorter because the sun is higher.

∙ 14y agoI understand that the closer the object to the light source the sharper the shadow and visa versa or depending on the intensity of the light source the more intense the light the sharper the shadow. However I have recently had a shadow problem that has made me question this. I have tried 3 different materials of almost equal dimensions and found that out of the 3 materials (cardboard, wood, aluminum) I found that aluminum produces a significantly sharper shadow. I can not explain this.......
