Monday October 16, 2006 Hong Kong In Ella Koon Yan Na's new ad for Reenex Neo-Collagen skincare products, the she is portrayed like a butterfly undergoing metamorphosis. Ella's image is quite groundbreaking and to protect Ella's privacy, the set was cleared during the filming process. To portray the product's ability to transform the skin into a much younger state, Ella's image was similiar to a newborn child. Although Ella took all necessary precautions to avoid overexposure, but the advertisers took extra steps to ensure restricted access to the set. The production crew members were not allowed to bring any cameras, cell phones, nor recording devices with them. Only the main photographer and make-up artist were allowed in close vicinity of Ella. Ella was at the ad shoot from 4 pm to 6 am in the morning. During filming, Ella was in a crouching position, using only her legs to block her torso. Two fans were blowing on set to create the fabric's fluid movement. credits: Dramasian, asianfanatics.
