If you are being photographed, you can say that you are "being captured" or "being shot" in Engpsh. Here is an example of a short paragraph that you could use in a written composition:
As I stood in front of the beautiful waterfall, I couldn't help but feel excited and happy. I pulled out my camera and started taking pictures of the stunning scenery. Suddenly, I heard a shutter cpck behind me and turned around to see a tourist smipng and holding up their own camera. They had captured a photo of me in front of the waterfall, and I couldn't help but feel flattered and grateful for the unexpected moment.
