One more for comparison, this time a close up of Sargent's portrait of Henry James next to a very similar photograph.
Like other portrait artists of his time, Sargent didn't rely on photographs or measurements to create a likeness. Instead he worked directly from the model, more interested in the gesture than the measurement of the features. He observed his patrons and through dialogue became intimately knowledgeable of their character.
Many artists might be worried that rapidly changing technological advancements will eliminate the need for high quality art. While likeness can and will be easily captured by our cameras and created by our computers, they will never replace the artist touch and the selective ability to draw out character.

Please enjoy this following excerpt I found taken from the White House Historical Association regarding Sargent's commission of Roosevelt.
"In Roosevelt's official presidential portrait Sargent seized upon two of the President's most salient characteristics, physical vitality and a self-assurance bordering on arrogance, and he painted a tour de force of nuanced blacks, grays, browns, and creams. . . .
"The famous expatriate artist arrived in America in January 1903 and soon received a letter from Roosevelt inviting him to live in the White House during the month of February to work on the portrait. . . .
"Together [Sargent and Roosevelt] toured the White House while Sargent looked for proper light and a good pose. . . . As Roosevelt led the way upstairs, so the story goes, he said, 'The trouble with you Sargent, is that you don't know what you want.' 'No,' replied the artist, "the trouble, Mr. President, is that you don't know what a pose means.' Roosevelt turned sharply back, grasped the newel-post and snapped, 'Don't I!' 'Don't move an inch. You've got it now,' responded Sargent. . . .
"Sargent formalized the pose as an official portrait demands, but the highly colored face and hand bring the painting to vivid life. . . . The expression--a near scowl with narrowed eyes focused on the view--and the vigorously modeled head compel attention and respect."
