What is the so-called sketch in photography?

There is no clear definition of sketch photography, and some books about sketch photography are written in combination with macro photography or still life photography, that is to say, there is no clear definition of its definition. For a so-called sketch photography, it is more subjective factors for photographers and viewers to call her that way.

So it is called "photographic sketch" because the main body of these works is too "small". They are either a still life, a flower, a grass, a fruit, or a small life, or even just a piece of new green with one or two leaves. The "smallness" of "prose" is just relative to macro-masterpieces or major themes. Without their significance, ideology and artistry, it must be poor (not meaningless). On the contrary, it is not known whether you will suddenly feel the feeling of "seeing the big from the small" when playing.
