Did you know that 50-80% of our communication is actually non-vocal?
Facial expressions or body movements often communicate more than we actually voice so let's read some body language and put together an image guide to body signs, signals and gestures.
As you all know, the body language is the transmission of your feelings, attitudes, and moods. Show us how you feel using your body. Are you happy? Are you nervous? Are you bored? We're aiming for a comprehensive photo reading of the body language so remember that it's not all in the face. Don't overlook the hands, the body movements, the arms, the legs, the voice pitch of your models. If you're unhappy, frown or pout. If you're angry, clench your fists or grind your teeth. If you're in love, blush. If you're scared, scream. All face-to-face interaction involve reading the body language of the others so interpret your addressee's hands in pockets, feet dangling, winking or head nodding. It's easy! There may be cultural differences of course but we all know what rolling eyes usually mean.
There will be smiles and thumbs up for the winners as we award $300 for the first place, $200 for the second place and $100 for the third place. They won't need body language to express their happiness as the Dreamstime branded t-shirts they'll receive will say it all.
