Does the focus plane language have the same meaning as montage? Why? There are also comments on the use of lens language and montage in The Piano of Steel.

There is a difference between focus plane language and montage. The focal plane language includes montage, but montage cannot cover the lens language.

The so-called lens language refers to the full, medium and close-up freeze, push, pull, shake, move and their combinations of the lens. Montage mainly refers to the combination of different time, space, angle or other performance factors in lens editing. This is not possible in a fixed lens language.

I've never seen a steel piano, and it's not good to add comments.

After reading your question, I downloaded the piano of steel. This movie really touched me. If nothing else, it can be said that the whole film tells the simplest and most profound truth with the simplest language and the simplest lens. In addition to the full, middle and close-up freeze-frames, the whole film uses more movement: horizontal movement, also called heel. Only two pushes and one pull, only the pull lens uses a little perspective and focal length change. At the end of the film, when the hero and heroine get married and dance, they use a montage technique to show their indomitable spirit and no longer use gorgeous camera language, which leaves a very deep impression on people. This reminds me of the film "North Wall", which is also a very plain lens language. There is no nonsense and no obvious application of photography technology. Directors and photographers are serious, simple and tasteful people. Only by using this simplest language can we tell the deepest truth in life. Thank you for recommending this film.
