神经网络能做很多事，但它只能基于你提供的内容工作。好的照片会生成相似、稳定的视频；差的照片会导致脸部模糊和动作怪异。以下是选择图片的简单规则，用于 上传你的照片.
The main rule: the face must be visible
The service looks for one adult face and compares it with your selfie. So the picture should show the whole face, not a profile against a dark background or a face hidden by hair. The face should not be smaller than about 70 pixels wide, and in practice the larger the better.
Light decides
The best light is soft daylight from a window, in front or from the side. Avoid:
- 脸上刺眼的亮斑和深深的阴影；
- 逆光，当你背对窗户站立时；
- night shots with a flash, they are flat and grainy;
- 会改变你肤色的彩色灯。
Angle and pose
胸部以上或腰部以上的肖像照效果很好，面部正对或微微侧转。全身照也可以，但脸部会显得较小，相似度会下降。如果你想展示身材的场景，选择腰部以上的照片：这样能给网络提供更多关于身体和衣着的信息。中性表情或淡淡微笑比夸张的鬼脸更好。
画面中只能有一个人。
Group photos will not work: the service refuses at once if there is more than one face. Crop the picture or pick another. Reflections in mirrors and people in the background are best removed, sometimes they count as a second face.
Ten-point checklist
- 整张脸都可见，没有阴影遮住半边。
- 画面中只有你。
- The photo is sharp, the face in focus.
- 没有厚重的滤镜或美颜修饰。
- No dark glasses, mask or hat hiding your forehead.
- You look at the camera or slightly aside.
- Light is soft, skin colour is natural.
- 文件最大 8 MB，支持 JPG、PNG 或 WebP。
- You are 21 or older and the picture is recent.
- The photo is your own.
糟糕的照片及其失败原因
- Group selfie: several faces, instant refusal.
- Night flash shot: flat face and red eyes get reproduced as real features.
- Distant shot: the face is a few pixels and likeness is lost.
- Photo with a rejuvenating filter: the filter changes the face, the camera selfie has none, so the match can fail.
- 侧面照：一侧不可见，网络只能猜测。
如何在两分钟内拍出一张好照片
- Face a window in daytime, about a metre away.
- 将手机举到与眼睛齐平的高度，稍微靠上一点。
- Wipe the lens: fingerprints blur the picture.
- 拍三到五张，保留最清晰的那张。
- Turn off the "beauty" mode.

Clothes, beard, glasses, makeup
Clothes on the photo hardly matter, because in the clip you can wear anything the description says. A plain background helps the network separate you from it. Beard and glasses are fine: upload how you normally look and take the selfie the same way. Bright makeup on the photo and none on the selfie can lower the match.
为什么相似度有时低于预期
Three reasons: weak light and noise on the photo, a complicated action in the description that moves the face a lot, and small differences between photo and selfie such as another haircut. All three are solved by choosing a simpler action and closer pictures.
Short answers
Can I upload a photo in swimwear?
服装并不禁止，你只需要独自一人且面部可见。视频中的服装来自描述。
Does a screenshot from a video call work?
If quality is good and the face is sharp, yes, but call compression often ruins detail.
