The essence of photography is realistic. Photography can of course organize various beautiful pictures like painting, but in comparison, it may be more important to analyze and study its expression method based on the essence of realism. Documentary photography is widely valued in China and has achieved quite good results. It is precisely because documentary photography makes full use of the realistic function of photography; and news photography and reportage photography are playing an increasingly important role in today's social development process. The important role is all because it fully reflects the special power of photography in realism. However, the technical skills of realistic photography in terms of theme expression are not sufficiently studied and even less systematically summarized. This is exactly what I want to discuss with you on this important topic.

The basic operation of realistic photography, whether it is artistic creation or non-artistic photography, is to directly face the living real world. All images formed on the screen, including all details, are all what they are in real life. People even have an unquestionable principle about this, that is, no fraud is allowed in everything captured on the screen. In fact, this is the basic characteristic of all realistic photography.

If compared with painting, it can be said that realistic photography is a method of capturing a certain moment in real life to ultimately achieve artistic or emotional expression. Its outstanding feature is the organic organization of realistic situations (even instantaneous organization); while painting is dedicated to depicting ideal pictures and achieving artistic or emotional expression through various rendering methods.

There are a few points that must be made clear:

1. Real scenes in life, rather than images that are finally formed after conception;

2. Capture A certain moment, rather than carving out a picture;

3. The momentary organization of situations, rather than carefully designed arrangements.

And the most important point is that this kind of scene captured from real life, as well as the picture frozen in an instant, must serve a certain theme, and it is definitely not what it captures.
