Abstract: According to embodiments of the present disclosure, a method, apparatus, device and storage medium for image shooting are provided. The method comprises presenting a first shooting page in an asynchronous shooting mode. The first shooting page includes a first shooting window for presenting a first scene captured by a first camera of a terminal device. The method further comprises in response to the first camera completing shooting of a first image, presenting a second shooting page comprising a second shooting window and a first image window. The second shooting window presents a second scene captured by a second camera different from the first camera. The first image window presents the first image. The method further comprises capturing a second image by the second camera while the second shooting page being presented. In this way, flexible and interesting image shooting experience is provided.

Abstract: Provided are an information processing method, an electronic device, and a storage medium. The method includes the following: in response to a trigger instruction from a current user for a first user in an association user list, the association user list is dynamically updated and displayed; where the association user list corresponds to the current user, and the step in which the association user list is dynamically updated includes that at least one second user is determined according to the first user, and the association user list is updated based on the at least one second user; where the at least one second user is associated with the first user.
