The 42 year old was glammed-up and photo-ready for her fragrance launch in Miami, Florida at Saturday's (07Nov09) Make-A-Wish Ball.
However, her manager Peter Asher requested photographers shoot her only with a "ring flash", known to eliminate shadows and imperfections.
According to the New York Post, Asher banned all lensmen without a ring flash from the event, prompting several photographers to walk out.
Anderson's spokesperson confirms the star made the request, telling the New York Post the flash requirement "is something Pamela wanted".
However, organisers at Make-A-Wish are attempting to cool down the controversy, adding: "In-house photographers were told to use the ring light, but our red carpet was issue-free."
