The relatively simple way for gta5 to shoot the princess is to directly call out the mobile phone (up arrow key or press the mouse wheel key) and then find a camera-like application in the mobile phone application to directly enter the shooting mode. Just follow the prompts and take photos directly. Press the up arrow key or the mouse wheel key to bring up the mobile phone page in the lower right corner, find the camera, click with the left mouse button to enter, and follow the prompts to shoot directly.
