Most people don’t really think about their smile too much until you see about fifty versions of it in front of you, and you have to pick the ones you like the most! When getting headshot images, your smile or your ‘serious face’ are important because facial expression is a key aspect to rely the message you want. Too big of a smile, too small, close mouth or open mouth – are all things to consider, as well as image use and target audience. Is it more imporant to appear open and friendly – or reserved and traditional? Do you need to appear relaxed and fun? Body language, posture and outfit are also key factors that all should be used to enhance your appearance and message.
It is also a great idea to get at least a small variety of images so you can choose the most appropriate one for each purpose, such as a formal business card and linked-in image but a more open/smiley facebook profile photo.
