With a portrait you either need them to be looking into-or significantly away from-the camera. 拍肖像时,拍摄对象的眼睛可以看着相机,或者有意识地不看相机。
The check and investigation should adopt scatheless technology as for instance geological radars survey technology, draw a portrait camera work, etc. 检查和调查应采用以无损探伤技术为主体,如地质雷达探测技术、画像摄影技术等。
