I have a deep knowledge of PS, and I have learned a lot from watching many photographers' portrait works, but I have no shooting experience. What should I do if I want to shoot on location?

I think what you should do on location should be the process of location shooting and what you should pay attention to. If I guess correctly, you can look down.

After you and the person you want to shoot arrive at the shooting location, you can first think about where to shoot and how to shoot when she is putting on makeup. If you are familiar with the shooting location before, you can directly consider the beauty of the model. Of course, before that, you still have to think about the content and theme of this year's shooting, and then consider how to shoot it. As for the style, of course, it should be suitable for the theme you express, but try to change several styles, otherwise it will bind your mind.

It is suggested to bring a telephoto lens or a fixed-focus lens and add a wide-angle lens for location shooting hardware. Bring a flash and a reflector. Personally, I think flash is more important, not only to fill the light, but also to create a personalized lighting effect. The reflector must be worn, which can play another role in many cases, such as blocking direct sunlight (using a soft surface).

Location shooting is nothing more than these things, and it is nothing to bring enough batteries and cards. If you mean composition and framing, I can't help you here. As the brother upstairs said, these things need you to practice and think more.
