Abstract: Embodiments of the present disclosure allow user experience of photographing to be improved. In operation, it is determined whether a picture composition of a first object and a second object needs to be adjusted based on a predefined composition rule. If the picture composition needs to be adjusted, an adjusting pattern is determined based on the predefined composition rule. Then, the adjusting pattern is provided to a user to indicate the user to adjust the picture composition based on thereon.

Abstract: The present invention provides a mechanism for generating an initial copy in replication initialization. A request is received to replicate a source volume from a source node to a target node so as to generate the initial copy of the source volume in the target node. With respect to a current source data block of at least one source data block contained in the source volume, a search in the target node is performed for a target data block corresponding to the current source data block. Responsive to identifying the target data block, the initial copy of the source volume in the target node is updated using the target data block with the information from the current source data block.

Abstract: A data storage system, and a method for accessing data in a data storage system, wherein the data storage system comprises at least a first volume and a second volume, and the first volume and the second volume remain consistent by a synchronous copy relationship, the method comprising: setting a virtual unique identifier of the second volume as a unique identifier of the first volume; creating a first path from a host to the first volume and a second path from the host to the second volume by using the unique identifier of the first volume; accessing data by using the first path from the host to the first volume; and setting the second path from the host to the second volume as unavailable.
