Themes can be sorted out by induction. It needs a powerful editor for many similar photos you have taken. If all your photos are school scenery, then the theme is school scenery. Your friend is right. Taking a group photo is more important, and the finer the score of a group, the better.

In the era when everyone is a photographer, photographers, like drivers, are not only a profession, but also everyone's hobbies and necessary skills.

Apart from punching in and taking selfies, everything we can see can be the object of photography, as long as you observe the details and appreciate the beauty of the picture and the significance of solidification time. List shooting topics:

Architectural photography, macro photography, starry sky photography, natural scenery photography? Wildlife photography, pet photography, microphotography? Portrait of people, children's photography, humanistic street photography, urban landscape photography? Museum photography products photography news photography industry photography?

There are many more, please add them at any time.

In addition to these big aspects, any small subdivision and thing can be a topic of shooting, such as shooting clouds, lightning, gems, long-term fixed scenes, flowering process, shooting scenes in professional fields and so on.

In addition, new photographic equipment and technology have also broadened the boundaries and forms of photography and increased the interest of photography, such as VR technology, 360-degree and panoramic photos taken by stitching technology, aerial photography by drone technology and so on.

What I want to say is that for ordinary photographers, while shooting daily subjects, they can also shoot extraordinary works by focusing on small subdivisions for a long time and properly using some photography skills and new photography techniques.
