Users have been reporting that Lenovo Photo Master is pretty useless because it doesn't offer good features. However, open the software, then use File > Open to open a supported file format and after this procedure, use the features available on the software to enhance or modify your images. Go to Help > Help topics to learn more about the program's functionality.
Additionally, use other photo editors that are more powerful and more easier to use: http://software.informer.com/search/photo+editor
