Can't artists draw exactly the same pictures with photos as reference? For example, Figure 1.

Because photos are also divided, such as paid photos, or unique to the owner, the photos taken by the photographer are all his own. If you use someone else's photo as a template without permission, it is equivalent to infringement. In Japan, there is a plagiarism post, which I saw a long time ago. Many of his works came from a paid photo online and were used without permission.

For example, someone takes your photo for secondary processing, and then makes a name, a popularity or even a sum of money, and then finally doesn't tell you. Isn't this a violation of your portrait rights?

Similarly, the photo was taken by the photographer himself, and the copyright of this photo was in the photographer's hand. Then someone directly copied the photo and changed it twice. Without marking the original picture, he directly said that he was original. Is it too much?
