With the development of times and cultural aesthetics，typology photography is no longer just a means of recording.Typology has gradually become an important method in photography creation.Typology photography is widely used in photography creation because of its unique inductive group，the epitome of the era，and the visual impact of unified picture content.This article will discuss the role of typology in inducing groups in photography and enhancing visual impact.

1.The role of inductive groups in typology

Typology plays a role in the inductive group and the environment of the times in portrait photography.This is not only conducive to the combing and archiving of the works，but also greatly helps the author to explore ideas and create inspirations during the creation，helping the author to enrich the content and plump the works.And it is more conducive to the performance and expression of the theme.

At the beginning of the 20th century，the portrait photography of the famous German photographer August Sander was very typed.He called his filming plan "the people of the twentieth century" and planned to take portraits of people from all walks of life and various social classes in Germany.He pursues "precise photography"，a clear-cut，straightforward style with reluctant portrait photography.His work is based on the specific regional environment system that photographers are familiar with in the specific era of recording local people，whether intentional or not，his works.They all reveal the qualities shared by the characters in his time.

In China，there are also excellent photographers like Sander.The Song Dynasty was originally a miner who had been working as a miner for six years.The "coal blacks" brothers he photographed were his workers.The Song Dynasty did not consider too much when shooting.Each miner is a relatively independent individual，with different appearances in the same background environment.But when the works of the Song Dynasty were made into exhibitions，the viewers read out the prominent points of the miners' character，the miners' total temperament，tenacity，and their personal character.Which person may be subtle and steady，who is willing to work hard，who is Perhaps when work is lazy，it is clear at a glance.The Song Dynasty captured the penetrating gaze in the form of portraits，showing the different personalities of the miners.The uniform white abstraction background，the oppressive composition，strengthen the characters' eyes and push the characters' faces，and show each character intuitively to the audience.The miners he photographed are not only the miners themselves，but also represent this era.The epitome of this group.

2.Typological photography strong visual impact

In the creation of photography，not only the role of recording and induction，but also the large-scale type shooting of the same kind of subjects，similar subjects and the same theme through time accumulation will greatly enhance the visual effect and communication effect of the works.

A family portrait may not be called a "photograph"，but if a family photographs a family portrait for ten or even twenty years in the same environment，it will be a very shocking picture.In such a set of photos，we will intuitively feel the traces of time passing through in people and the environment，the changes in the appearance of each person，the changes in the personnel throughout the family，the development of the interior environment with the development of the times，and so on...When these photos are put together，there is no need for gorgeous decoration，no other language is required，and the charm of the image itself will infect the audience.

The pictures taken in this way are uniform and neat，have a sense of series，and are easier to expand in later creation.At the same time，although each of these photos is an excellent single photo，the accumulation of the number of photos has greatly increased the visual impact and appeal of the photos.Typology photography is an objective and rich sense of creation.It is not only a mechanical record of the scene，but a close-up representation of the characteristics of the subject after summarizing the characteristics of the subject.This kind of photography technique allows viewers to see the similarities and differences between multiple photos at a glance.This is in the literature recording，inductive group，the spirit of the era，and the rich content of the unified picture elements.It plays a vital role in the very common and practical way of shooting when creating photography.
