Is it necessary for photographers to learn later?

You do this in your spare time. You must make sure whether you like this PS technology. Give up if you don't like it. There is nothing to miss. If you like it, stick to further study, such as learning stereo photography technology and grating stereo imaging technology. As the saying goes, after ten years of grinding a sword, Mount Tai will not dare to stop it, as long as you are determined to have a bright future.
