Learn how models project their inner beauty
The most important point to remember is that your true beauty exists in your inner energy, and that you project that energy whenever your pose for a photo. You project your inner energy whenever anyone takes your photo, even if you are unaware of it. One secret that models have is that they understand how to project their inner beauty. They know how to express their confidence and well being and inner love. Most of us have to learn this. Professional models had to learn and practice this as well. Models have had time to practice and develop this skill. And it actually is a skill.
You can actually feel the joy in your heart as you smile
Next, get a chair, and put one foot on the chair, and let your arms rest naturally on your knees. Close your eyes, take a breath, exhale, and smile. This is a relaxed yet sophisticated pose. If your friend is taking your photo, have her take it only of your upper body, from your torso to the top of your head. Have her count, one, two, three, and on three, open your eyes and smile the moment before she takes the photo. When you do it correctly you can actually feel an inner shift - you can feel your energy rise from your heart area to and through your smile and to and through your eyes.
There is a saying that "the eyes are the windows to the soul." When a photograph is taken of you, you are offering your love and goodness to the photograph - to others - to the world. This is a beautiful exercise which helps your energy flow upward and out - so that when you greet others, you are offering this love and goodness and joy to them. In truth, you are experiencing it for yourself and sharing it with all.
