I have been playing photography for many years, and I am very impressed when I see the magnificent scenery of the masters. I often think: What kind of scenery is a good film, based on what criteria to judge? Landscape photography has changed so much that it seems difficult to find a unified evaluation standard.
Some people talk about photography, and the description of photography is unbelievable. I think it is about telling myths, not about photography. Only by being able to simplify complicated things, the general public can understand that it is correct.
To put it simply, landscape photography actually has four words: "combination of motion and static."
Someone may ask immediately, just this, I already knew it, this is not a secret. Indeed, these four words are estimated by the Chinese, but in photography, you really wonder what is moving, what is static, why do you want to combine statics and movements?
This is to start with the visual characteristics of the human eye. The human eye is more sensitive to dynamic objects. The human eye will be tired of no change for more than 5 seconds, start to look away and start looking for change. For example, a piece of white paper, you stare at it, no more than 5 seconds, you start visual fatigue. At this time, draw a black dot on the white paper, your eyes will be more attractive than the past, and the impression of the black spots will be more profound.
A good landscape, confession, the first is to please your eyes and brain. Therefore, landscape photography must be "combined with movement and static."
So what is moving in a photo, what is static? As we all know, the photo is static, it is a moment of solidification. So what is moving in a static photo? Simply speaking, it is "change", which means "unusual difference."
This change is mainly reflected by the color:
The trees, grass, sky, and lake in the photo are reflected in different colors.
Sample 1:
In this photo, the sea and sky are connected in one color, the pier becomes a change in this photo, and the warm light becomes a change in blue. At this time, Haitian is "quiet" and the pier becomes "moving."
