Narrator: THE WORD "PHOTOGRAPH" COMES FROM TWO GREEK WORDS

BY BEING ABLE TO PRODUCE A WIDE RANGE OF TONAL AND COLOR VALUES.

VALUE IS HOW LIGHT OR DARK A GIVEN COLOR OR HUE IS.

VALUES CAN BE BETTER UNDERSTOOD WHEN THEY ARE VISUALIZED

HERE'S THE VALUE SCALE FOR THIS GRAY TONE.

IT RANGES FROM PURE WHITE TO ABSOLUTE BLACK

ANY HUE OR TONE HAS A SIMILAR SCALE FROM DARK TO LIGHT.

DIFFERENT VALUES ARE CREATED BY LIGHTENING THE HUE.

WHEN AN ARTWORK HAS MANY TONES IN BETWEEN BLACK AND WHITE,

FOR INSTANCE, IN THIS PHOTOGRAPH BY NICHOLAS NIXON,

NOTICE HOW MANY DIFFERENT SHADES OF GRAY THERE ARE.

A HIGH-CONTRAST IMAGE, ON THE OTHER HAND,

WOULD HAVE VERY FEW TONAL VALUES BETWEEN BLACK AND WHITE,

LIKE THIS PHOTOGRAPH BY KENNETH JOSEPHSON.

NOTICE HOW THE VEINS IN THE LEAVES OF LETTUCE

COMPARE THAT WITH THIS PHOTOGRAPH OF BANANAS,

WHICH GIVES THE PHOTOGRAPH MUCH LESS CONTRAST.

AND IMPLIED TEXTURES CAN ALSO AFFECT HOW WE PERCEIVE VALUE.

THIS WATERCOLOR PAINTING'S BLACKS AREN'T NEARLY AS DARK.

NOTICE, TOO, HOW THE SHADING ISN'T AS SMOOTHLY BLENDED.

THE NEXT TIME YOU ARE LOOKING AT A PHOTOGRAPH,

TRY TO NOTICE HOW THE ARTIST IS RENDERING VALUE.

AND WHEN YOU'RE CREATING YOUR OWN ARTWORK,

WITH A VARIETY OF DIFFERENT MEDIUMS AND HUES

SO YOUR ARTWORK SHINES IN ITS OWN UNIQUE WAY.
