Including personal photo, wedding photography, all kinds of advertising photography, etc. Such works generally don't appreciate over time.

Artistic photography generally refers to photography and creation that does not take business as the main purpose, and its value performance is not immediate. Such as news photography, celebrity portrait photography, etc. It may be of little value at that time, but with the passage of time, this documentary or work with certain reserved value will become popular and its value will rise.
