The dimension information is lost from the screen on your phone but the size of part of an art piece is what constitutes the impression the painting has given you. For example, It’s like I have seen the picture of mona lisa thousands of times before I actually goto louvore’s museum to see the actual one. When I finally got to the exhibition rooms seing the mona lisa so small sitting in the center of the big room the impression and feeling I received from it is completely different from what I got by merely looking at a picture.
