Of course, when you are taking a picture of yourself, wear makeup and a flattering outfit. You can get practical advice about light and camera angles if you click this link:
How to Look Good in Pictures, 11 steps.
Hey guys, you don't need to bother with the 11 steps, if you read what Em has to say, based on experience.
First of all, you need to have something on your mind, not your camera.
Banish the vanity thoughts like should I have put on more lipstick? should I have worn a simpler outfit?
Ignore the discomfort, like my eye itches, or it's tricky to smile when the sun is in my eyes.
Stop thinking about the fact that you are posing for a picture. On and on goes the train of your thoughts about you, your work, the things you have to do, and what to do if the picture turns out poorly. Stop all those thoughts.
If you want a smiling picture, remind yourself about something that happened recently that was fun, or something that made you laugh. If you want a serious face, recall a death that touched you -- you can even produce glistening tearful eyes it you dig in to one of your real sorrows. If a sad, serious face is wrong -- you want a thoughtful or hopeful or confident look -- find a specific memory within yourself. Concentrate on it, and you'll probably have that face in your picture.
For some people this is acting -- finding within yourself a reality -- the reality becomes the play and the play script. The fact is, right now, as I am telling you how to look good in a photo, I am giving you a crash course in acting.
The stage is where you are. You are the stage manager and the director. The script is what you, the playwright, perceive as your "best" face.
Keep the thought hot, fresh, vivid, and you'll have a wonderful SELFIE -- yes -- a photo of the real you -- the handsomest you -- the you that you're proud of being.
