Besides dressing table, there is another explanation, also called dressing table, which refers to the mirror assembly used in the camera. This "stage" has two main functions. First, it can reflect light to the viewfinder and the focal plane of the camera, helping the photographer to adjust parameters such as focal length and exposure; Secondly, this kind of mirror can form reflection inside the lens mirror through its unique structure, so that the camera functions such as autofocus and anti-shake can operate normally.
"Mirror Stage" can also be used in metaphor to express a way of thinking that reflects one's own shortcomings. This mode of thinking usually means that people reflect on their words and deeds and find out the problems and misunderstandings. This kind of "introspection" can make you get all-round and multi-angle understanding and improvement, so that you can make better progress and growth. Through the thinking mode of "mirror platform", people can show themselves a true and objective self and avoid affecting their progress because of personal self-limitation.
