If it is a selfie, the pixel is very important, and then the angle is also very important. Different angles will have different effects. Don't hold the camera too high. From that point of view, you are not the mainstream of rolling your eyes. Similarly, I don't want to look down at the camera, because your facial features will be poor and your face will be ugly. The camera should not be too close or too far away from your face. The suggested angle is the front or the camera is held to the right, and your expression will be natural. Then the light. If the light is too dark, it will look very dark, the skin will be poor, and the five senses will look dark. It is recommended to take photos in soft light environment, such as coffee shop. There is also the expression, don't exaggerate, don't be too stiff, you can smile and try to be natural. Finally, the background should not be too messy, not to mention horses! Sai! Dick. You can look in the mirror more often, look at the angle and expression, and study which angle and expression are better.
