This week Lindsay Lohan went to jail and had to take yet another of one of the most unforgiving kinds of pictures a celebrity can take: a mug shot. Celebrities regularly have to submit to these oft-horribly lit photographic tortures, but seldom look prepared for such a close-up. So we rang up makeup artist Mally Roncal, whose clients include Beyoncé, Teri Hatcher, Celine Dion, and Joss Stone, to find out how, beauty-wise, celebrities like LiLo could have taken a better mug shot. Read ahead for her thoughts on the mug shots of Lohan, Mischa Barton, Chace Crawford, and others, and pick up a few practical tips for taking either a great mug shot (God forbid) of your own one day, or just a great badly lit, close-up head shot at any old party. Your Twitpics will never be the same!
