MILWAUKEEA WITI News camera crew spent 30 minutes inconspicuously following an overweight woman at the Henry W. Maier Festival Park Monday to capture footage for an upcoming segment on obesity. "It's hard to get anyone to agree to be filmed to illustrate what a fat person looks like," cameraman Doug Kovalik said, nonchalantly pointing his camera at an obese woman who was tugging at a pair of shorts bunched into her crotch while she ate a corn dog. "We avoid the whole mess by shooting them from behind or the neck down. It saves us the hassle of filling out release forms." Kovalik last used this discreet filming technique in May, when he captured B-roll at a local craft mall for a segment on managed care for the elderly.
