Compared with early portrait photographers, what are the differences in style? Urgent

Although modern photography art has different styles, the content is diverse for beginners. But one thing they all have in common is that they are in opposition to tradition. Use a new way of thinking to understand social life, study the objects of photography from a new perspective, and show the diversification of photography creation, including new changes in the value of photography art. If there's one thing about it, it's the variety of options. Cross-use multiple forms of visual language, including photos, drawings and text, to express ideas. Modern photography is characterized by seeking novelty and change. They are constantly exploring areas that have never been explored before, thus inevitably bringing about innovations in concepts or forms. "Modern" is not just an expression of time, but its artistic style, which is characterized by its rebellion against traditional photography.
