带座椅和彩色灯光的绿幕演播厅图片

In the middle of the stage at the domestic large?language?model launch event, a super?wide aspect?ratio screen displays pure green with no shadows or text, facilitating post?production cut?outs and content replacement. The venue has a dark tone with empty seats arranged neatly and no people. The top truss lighting system features a blue?purple gradient ambient light effect. The main subject is centered, occupying three?quarters of the frame without extending beyond the screen. 16:9 landscape, realistic tech launch photography style.
