I have not visited product promotion events for a period of time. While I got a day off on a Monday for a leisure photo walk, I encountered a sport wear promotion event organized by Adidas.
They also invited Miss Charlene Choi of "Twins" http://en.wikipedia.org/wiki/Charlene_Choi to promote the new sport-wear series. Just spent rather short time in the venue due to too many people around.

Here are some snapshots of the event. All are no flash shots captured using high ISO and available light.
