This is an App that controls the DSLR camera via USB. After connecting to the camera, you can monitor the camera's real-time image and control the camera's: exposure, file format, white balance, shooting mode, ratio, etc. It also supports transferring photos taken on the camera to the mobile phone, so that the camera can take pictures without inserting a SD card, and the photos will be saved to the mobile phone after taking them. This is the first version of the App. Currently it only supports Sony cameras. Canon and Nikon will also support it in the future, so stay tuned!
