6) In general, try to avoid being photographed from poor angles
… Especially from below. Having your body turned slightly so that you are 3/4 facing the camera is a good way to get the best angle. Ideally, have photos taken from above -the camera should never be below your chin.
7) Raise your chin slightly
To hide a double chin, forget about adopting strange angles, and just hold your head a little higher. Moving your face slightly towards the camera will also help your jaw appear more defined. Finally, relax your shoulders. Sticking your tongue to your palette also works very well.
8) And for the smile
Don’t smile too much -no one wants to see your gums! Try to be natural and relaxed. Think about someone you love, a happy memory, or the good times you are currently experiencing -the emotion will come out in the photo. Keep your tongue behind your teeth to avoid tense or fake looking smiles.
Many professionals advise “smiling with your eyes”, meaning gently crinkling your eyes to make the half moon shapes under your eyes appear. And if you have the habit of saying “cheese”, replace it with the word “money”, which highlights the apples of your cheeks better, makes your eyes smile and gently raises the corners of your mouth.
9) For group photos, don’t stand too close to the camera
If you are close to the camera, you will look disproportionately larger than the others. The trick is to all stand at the same level, for optimal results.
10) Pay particular attention to the lighting

If the light is above you, it will highlight all your little imperfections and create annoying shadows on your face. The ideal is to make sure that the light comes from opposite you, in as much as possible. And to avoid red eyes, look at the light source before taking the photo. Your eyes will thus get less of a shock from the flash (and it’s always better not to look like a frightened owl in a photo!)
