Silhouette Cutting for Fashion Boutique

I always like to do event for fashion boutique, because there are always able to meet nice guests and beautiful real fashion models ;pAs an Asian, I am not so tall especially if taking photo with those professional fashion models ;p
Usually in such event I having high chances to met many tall guests in the event as well; there are a way to do silhouette cutting for them to ensure the scale of the portrait silhouette cutting is still in the right proportion ;p
