Why is the finished sketch taken by the camera not as good as the reality?

The difference between sketch and photography is very simple, one is hand-painted and the other is real. Sketch and photography are both realistic from the naked eye's point of view, and both objectively express the content of the picture, but hand-drawn expression and photography are different types after all. If you use photography to represent the same picture, it is very fast and convenient, and it can realistically represent the real situation of the object. However, photography is industrialized, and it also shows some flaws, which affect the aesthetic feeling of composition and even the content of the picture. Although the speed of hand-drawing is far less than that of photography, it is full of artistic flavor of natural handwork and its value is higher than that of photography. Hand-drawing can directly reveal the elements of art and beautify the visual content, composition and texture of the picture. Remove the defective part of the picture directly.

Photography also belongs to the art category. To put it bluntly, photography is photography. It is relatively difficult to contrast the value and existence of art with photography. The content of some excellent and eye-catching photography works is often very simple, and the composition, content and elements of the picture are exaggerated beyond imagination. The bright colors sometimes give people an unforgettable feeling.
