What you said is fine. "Professional Photography Training Course" is fine as well.

I would maybe call it either Professional Photographer Course or Professional Photographer Training, as training and course express somewhat similar ideas. But you can also use: Professional Photographer Training Course A more informal version could be: Take photos like a pro!

Thanks for explaining the details, Richard!

A course may provide information and knowledge (this is also called "education"), however, some courses will also help you to develop a skill (the ability to do something/to do work). For example, I could learn all the names of the parts of a camera and that would be education/knowledge, but it does not mean that I will be able to (have the skill to) use the camera or operate the camera. So, a course may or may not include "training" (skill development).
