For a symmetrical composition along the central axis (a classic angle), position yourself on the central axis pathway directly south of the Yongding Gate Tower, with the subject in the middle of the pathway.

Use a wide-angle lens (16-35mm) to capture the tower and the depth of the pathway from a low angle. On a sunny day, shoot with the light coming from behind you. On a rainy day, capture the reflection of the tower. The best times to shoot are one hour after sunrise or during the blue hour before sunset. For the best reflection, choose a time when the water is calm, and consider using a long exposure for a smoother effect.

Yongdingmen - Front Gate

Composition Rules: Apply the Rule of Thirds to arrange the Yongding Gate ancient architecture, enhancing the balance of the image. Use the structure of the gate arch as leading lines to guide the viewer’s eye. Angle and Lens: Shoot from a low angle to showcase the grandeur of Yongding Gate. Use a wide-angle lens to capture the entire scene, adding depth to the central axis and the ancient architecture.

Model Pose: Place the model in the foreground to add a human touch. Design engaging poses to enhance the趣味性of the photo.

Shoot during the golden hours of early morning or evening to utilize soft lighting and highlight the layers of the Forbidden City. Perform color correction to enhance the light and color of Yongding Gate. Adjust the contrast to make the details clearer. 

(Note: "趣味性" can be translated as "fun" or "interest" in this context. I have chosen "fun" for a more natural feel in English.)
