Battle of the Bulge
The story of President Bush's "wardrobe malfunction" just won't go away. Salon now has a Nasa photo analyst on the case:



For the past week, while at home, using his own computers, and off the clock at Caltech and NASA, Nelson has been analyzing images of the president's back during the debates. A professional physicist and photo analyst for more than 30 years, he speaks earnestly and thoughtfully about his subject. "I am willing to stake my scientific reputation to the statement that Bush was wearing something under his jacket during the debate," he says. "This is not about a bad suit. And there's no way the bulge can be described as a wrinkled shirt."

[...]

Nelson used the computer software program Photoshop to enhance the texture in Bush's jacket. The process in no way alters the image but sharpens its edges and accents the creases and wrinkles. You've seen the process performed a hundred times on "CSI": pixelated images are magnified to reveal a clear definition of their shape.

Bruce Hapke, professor emeritus of planetary science in the department of geology and planetary science at the University of Pittsburgh, reviewed the Bush images employed by Nelson, whom he calls "a very highly respected scientist in his field." Hapke says Nelson's process of analyzing the images are the "exact same methods we use to analyze images taken by spacecraft of planetary surfaces. It does not introduce any artifacts into the picture in any way."

How can Nelson be certain there's some kind of mechanical device beneath Bush's jacket? It's all about light and shadows, he says. The angles at which the light in the studio hit Bush's jacket expose contours that fit no one's picture of human anatomy and wrinkled shirts. And Nelson compared the images to anatomy texts. He also experimented with wrinkling shirts in various configurations, wore them under his jacket under his bathroom light, and couldn't produce anything close to the Bush bulge.

Pay no attention to the man behind the curtain...
