Amy Adams looks at photographs of herself to avoid beauty disasters.
The 'Man of Steel' actress revealed she studies the ''inspirational'' photos with her styling team in order to make sure she never makes the same mistake twice.
Speaking to Britain's Marie Claire magazine, she revealed: ''It's part of my preparation for major red carpet events. That said, on one occasion a hair stylist made my hair enormous - but rather than freak out, I thought, 'I'm just going to take my big hair out for the night - you work it, girl.' ''
The 38-year-old actress - who is engaged to long-term partner Darren Le Gallo - claims her bizarre ritual has enabled her to ''understand what works and what will photograph well''.
Despite the redhead repeatedly gracing best-dressed lists, she also revealed she has made serious make-up faux-pas in the past.
She explained: ''I love black eyeliner in the inner corners of the eye, I tried it once and it made me look like a beady-eyed little beast. Instead, my make-up artist Stephen Sollitto applies individual lashes at the outer corners, to open up my eyes.''
As part of Hollywood's A-list, Amy is no stranger to pampering herself and follows a luxurious facial routine to get her skin glowing before glitzy events.
The star continued: ''I don't tamper with my skin before an important event. But in the run-up to the Golden Globes or the Oscars I'll have a facials with the wonderful Marion Simms at Skin Sense - a wellness centre in Beverly Hills.''
