The Portrait Photographer Finale
When you have delivered the photos to your client ask them for a testimonial. If you have done a good job they will tell other people about you. If they are not happy they will tell more people. So it goes without saying that you need to do a good job, your business depends on it! Be sure to get a model release that allows you to post their pictures on your website and social media profiles.
I hope this has helped and I also hope that some of my future clients have read this. I have a face for radio so I know exactly how you feel when confronted with a camera. Relax and enjoy the experience. A good portrait photographer will make it easy.
