There are some moments we wish we could stretch as long as possible. Life might not allow that. But with a photograph, the rules of time don't apply. A photograph is timeless. It captures who we are, the moment we are existing in right now, and all the feelings that come with it. Whether it is a candid photograph of a family day in the park, or a one-on-one session, a good portrait results from a good rapport between the photographer and the subject. Be your true self in front of the lens, and it will create a photo that communicates your true essence. And gives you all the "feels".
Just be yourself, and I'll take care of the rest.
