Any successful model knows that just staring blankly into a camera and having a pretty face is not nearly enough to be considered great at their job. The expressions you use when being photographed convey all sorts of emotions, and depending on the demands of the particular job you are doing, these expressions can make or break the success of the campaign. A photographer will often give you instructions and feedback on how you are posing and how your poses are translating on camera, but you can do your part by making sure you are working with them, rather than against their instructions. To save photographers the extra work of correcting everything you do, make sure you know your own face and how it moves before heading into a photo shoot. One of the best ways to master your expressions and movements is by doing mirror work. You certainly do not need to do mirror work for hours at a time, but spending a few minutes on it every day will gradually build up the muscle memory you need to master it and become a better model. Before long, you will be able to do any pose or expression on command and without much coaching, thanks to the mirror work you put into it. You will also instinctively know if a pose or expression you are doing looks awkward, based on the way it feels.
This is the first part of the guide where I will tell you secrets about posing. At the beginning we will focus only on a facial expression. In the next part I will tell you about a whole body.
In almost every modelling assignment, photographers need their models to convey some kind of emotion through their facial expression or body position. You can work on facial expressions by practising them in a mirror. Everything you feel is reflected in your face, and models need to be adept at projecting all the major emotions. Make a list of key emotions love, hate, sorrow, joy etc. After you have practised for a while, try out your skills on a friend and see if they can tell what emotion you are conveying.
