Can you make the Bad Times trend from one selfie?

The argument shows you from the head to the knees for the first ten seconds, then your face fills the screen at the lens. We tested a shoulder-up café selfie: the full-body frame kept his face, hair and sweater and filled in dark trousers, and the close-up at the lens looked like him.

So a selfie works best when:

• your face is sharp and facing the camera, because it ends up filling the screen;
• the light is even, with no sunglasses or heavy beauty filter;
• you're the only person in it.

If the outfit matters, say a costume, a uniform or your favourite jacket, use a photo that shows it. What isn't in the photo is made up to fit, so it won't be your actual jeans or shoes. More tips in which photo to use.

The first thing you get is a free picture of you right at the lens, made from your selfie. If it doesn't look like you, change the photo before filming the preview. If it does, the free 4-second preview shows you standing in the kitchen.
