What elements does a good photographic work need?

The four elements of a good photo: obvious theme, clear focus, saturated color and correct composition.

Why is an attractive photo attractive? It must have an attraction, and this attraction is the theme. It is also the place that can best express the meaning of this photo. Usually this theme point is also the focus of our lens. In order to highlight the theme, it is clear at a glance. This is the first thing we should think of before pressing the shutter.

We all know that the subject of a photo will not be clear if it is not in focus. Similarly, the vibration of the camera during shooting is also the main cause of blurred photos, which beginners should avoid. If possible, try to use a tripod or bracket, and try to keep the camera stable when pressing the shutter, otherwise use high-speed film or large aperture lens to improve the shutter speed. If you use a hand-held camera with a standard lens, it is recommended that the shutter speed be faster than1125 seconds. If you use a long lens, you should use a faster shutter.

Color saturation is probably the most uncontrollable factor for photographers. If you want to take colorful photos, not only the color of the subject itself should be beautiful, but also the light or lighting on the scene is more important. Secondly, the type of negative and the process of developing photos will affect the color saturation of photos. However, what most photographers can master and need to study is the accuracy of exposure, and the accuracy of exposure only depends on the skill of photometry. The camera's photometry skill is a university question, and many experienced photographers may not be able to fully master photometry. In order to prevent inaccurate exposure, many people adopt the method of surrounding exposure, that is, taking several underexposed and overexposed photos in addition to the exposure time that they think is correct. After the photos are developed, one of them must have the correct exposure or the most satisfactory exposure, which is often used by the author when photometry is not easy. For most excellent photographers, the technique of photometry is definitely worth our time to study, and we will talk about photometry again when we have the opportunity.

Composition is also a college problem, or it can be said that there is no knowledge. There are many books on the market devoted to composition, so you might as well buy one and have a look. In fact, the basic principle of composition is to look even, stable, comfortable and regular, and guide the line of sight to the theme point to avoid disorder, uneven left and right, top-heavy, and no visual focus because of too many themes. Under this principle, many composition methods have been developed, such as triangle composition, L-shaped composition and S-shaped composition. However, these composition methods are all fine arts. Therefore, the author thinks that these composition methods can be used for reference, but if you have your own views, you might as well jump out of the norms of books and faithfully express your feelings.
