What does photography mean?

Photographic sharpness is a kind of expressive force and clarity of figures or landscape details in photographic works. In photography, the definition of sharpness refers to the detail clarity and sharpness in the image. It is determined by the focus of the lens and the distance between the objects. The higher the definition of photography, the clearer the details and the more realistic it looks. Some photographers will choose to use a smaller aperture to get a deeper focus range, so as to get higher sharpness.

The use of photographic sharpness in different fields is slightly different. In portrait photography, photographers usually want to capture the details of the model's face and eyes, which requires high sharpness. In landscape photography, many photographers choose to use a smaller aperture, which can increase the depth of field, obtain a wider range of sharpness, and make all parts of the photo look clear. In macro photography, the photographer may need to use a large aperture and focus on a part of the petals to get better definition.

The sharpness of photography can also be enhanced by post-processing. In various post-softwares, improving sharpness can make images more vivid and clear. At this time, we need to pay attention to the size of the processing range. Excessive processing may have the opposite effect, resulting in jagged photos. In addition, the portrait layer or Gaussian blur layer can be used to soften the background, thus making the whole image more layered.
