Cheese is for eating.

It can be hard for both the subject and the photographer to get a natural unforced smile.
The subject needs to be relaxed and the photographer needs to make the subject feel relaxed. There are lots of methods for this and saying cheese or being asked to “smile” are not one of these.
You can help yourself (and the photographer) by being relaxed and remembering this is not life and death or a medical operation.
If you’re relaxed, it will reflect in the photos and help represent you in the best possible way.
There you have it, tip no 3 to help you, the paying customer, get the best out of your headshot shoot.
