What do you think is the practical value of photography?

I think the significance of photography lies in "feeling life and discovering the beauty of everything".

Because in fact, we don't notice many things in our daily life. We just see them instead of feeling them. When we pick up a camera (preferably a bulky SLR) and start looking for beauty, we will suddenly notice how vivid the gestures that we turn a blind eye to are. Photography is to record these beautiful scenery.
