There’s a magical art to capturing a great portrait picture, especially when the person you’re shooting is incredibly famous. One man who mastered this skill with spectacular success was Latvian born Philippe Halsman. In a career spanning more than three decades, he photographed such legends as Alfred Hitchcock, Judy Garland, Winston Churchill and Marilyn Monroe. Many of these portraits ended up on the cover of Life magazine. No wonder, then, that in 1958 he was listed in Popular Photography’s “World’s Ten Greatest Photographers”. Our favourite Halsman photo, however, though is something very special, Salvador DalĂ going all flower power.
