Acting naturally and naturally in front of the camera is something that is not easy to learn if you are prone to complexes. However, it is naturalness that gives the best results. Some training is indispensable here, but anything is possible: practice will allow you to feel free.
Love your looks, demeanor and voice
Psychologists and stage teachers point out that the main reason that people are shy in front of cameras lies in self-doubt and dissatisfaction with their appearance. Therefore, it is worth starting by working on your own self-esteem. Realize that you look great. If there is something that you are not happy with, work on it. For example, this is neatness and neatness: indeed, while working in front of the camera, such things will be too conspicuous. Make sure you always have the perfect manicure, great hairstyle and clean and tidy clothes.
Practice smiling in front of the mirror at home. Try different smiles and emotions. Try to change your posture, look casual, excited, happy. You will find interesting body positions and facial expressions, memorize them. Your body during filming is a tool that you must master to perfection. A sincere and open smile is something without which an actor or any public person simply cannot take place.
Dancing also helps to believe in yourself and make friends with your body. Dancers usually feel much more relaxed, they are confident in their figure and movements.
Practice
It takes practice to learn not only to be at ease, but also to be able to produce the desired effect. It is necessary for someone to film you from time to time, so that you can then review the result and note what you are doing wrong, which should be worked on. Practice combined with habit can get rid of complexes and turn any person into a professional.
At first, you can ask friends and relatives to film you, it can be anything: an impromptu interview or a rehearsal of your "show". But then you need the services of a professional operator. The point is that a good cinematographer, like a good photographer, is able to see in you something that most likely will not appear in a photograph taken by a layman.
Don't forget about acting classes. It is on them that you will learn the basics of how to properly hold in front of the camera. You should not rely only on independent work or only on courses, you should combine both.
If you want to learn how to stay in front of the camera not in order to constantly act as an actor, but, for example, to hold webinars from time to time, then it will be much easier for you. Rehearse your lectures in advance before giving them so that you do not read from one sheet of paper. Watch your gestures, avoid unnecessary gestures, do not fiddle with objects in your hands. Little things like this can help you deal with anxiety, but it's best to try to do it outside of the frame.
