Today, I participated in the shooting of the Celebration Boom-Boom Operation at Universal Studios Beijing. This time I am cosplaying Klee from Genshin Impact. To present the best state on site, I got up early in the morning to start preparing the makeup and styling. Klee's outfit has extremely many details: a red coat paired with white ruffled shorts and white stockings, and carrying that iconic square backpack, the overall volume is not small. The hat and wig require many hairpins to fix, and the elf ear props also need to be attached well, otherwise, they easily fall off while walking. Fischl's costume presents a different style: a black sleeveless dress paired with purple sleeves, plus the iconic eyepatch and stockings with dark patterns, bringing an overall mysterious temperament. We shot in front of a stone wall and artificial turf, and the site was arranged with green vines, red-orange flowers, and warm yellow lighting, creating a rich sense of visual layers and a strong holiday celebration atmosphere. During the interaction segment, we needed to make various actions according to the photographer's guidance. Sometimes it was me with both hands clenched into fists in front of my chest, or spreading my arms; Fischl would cooperate with me by putting one hand on her hip, or pointing her finger at the lens, and standing on tiptoe with one leg. We tried our best to showcase the character's personality traits in front of the lens. Klee is lively and active, so in expression management and body language, I tried my best to show that energetic feeling and maintain the infectious power of the smile. Fischl carries a confident temperament, requiring a good grasp of the tension in her expression. The entire shooting process required a high degree of concentration. Wearing these costumes and props, we needed to constantly pay attention to whether the wig was messy and whether the creases of the clothes affected the frame. Although the backpack looked good, wearing it for a long time would make our shoulders sore, and during rest intervals, we would help each other adjust props and costumes. When the photographer adjusted the camera positions and lighting, we would also exchange views on the connection of actions nearby. Duo shooting requires more tacit understanding than single shooting; eye contact or a tiny action coordination can make the sense of story in the photos completely different. There were tourists passing by on site, but we were all immersed in the characters' states. To capture the best light and shadow, we tried different standing positions in front of that stone wall. The light hitting the grayish-white bricks and stones, combined with the yellow light strips on the artificial turf, presented a very special layered sense. This Celebration Boom-Boom Operation gathered many friends who love ACGN culture. Conducting cosplay shooting here is not just completing a set of photos, but a process of immersing oneself in the characters and atmosphere. Showcasing favorite characters through the lens and completing interactions with a partner—this is where the fun of shooting lies. Although the entire process consumed energy, seeing the satisfying images presented in the camera made all the hard work worthwhile. Every time the shutter is pressed, it is a recreation of the characters and stories. Character restoration is not just putting on clothes, but lies in the precise control of expressions and actions, as well as the tacit cooperation with the partner. This event gave me more insights into the rhythm of on-site photography.
