LOS ANGELES — Priyanka Chopra had a problem: what to do with the light.

The actress, singer and latest in a long line of bombshell models for the clothing line Guess was standing in a walk-in closet in the penthouse suite of the Beverly Wilshire hotel, preparing for a photo shoot. “Maybe if we shot it like this,” she said, pushing sheer curtains aside and posing, Bond-girl like, in the sheet of sunlight that streamed through a floor-to-ceiling window (yes, the closet had a window; it also was bigger than some bedrooms).

“Good lighting is something that I know now, out of experience,” she said with a shrug.

Ms. Chopra, 31, tall and sultry, has been photographed and filmed enough times, appearing in more than 40 Bollywood movies since 2002, that such tricks of the trade have become second nature. She travels with an entourage (“When we walk into a room, it’s like ‘Ocean’s Twelve,’ ” she said of “Team P.C.”) and knows, without the aid of a mirror, when her dark, lustrous hair has been teased to just the right height.

And yet, while Ms. Chopra is one of India’s biggest stars, she can eat lunch on a busy Los Angeles sidewalk and not be approached by a single selfie-seeking fan. This may be about to change, though.
