In order to improve the comprehensive abilities of staff, Petromentor invited Instructor Zhao from its partner - China University of Petroleum (Beijing) to deliver an in-house training on photography. The theme was how to snapshot the very moments in training sessions with specific skills, including viewfinder、focusing、aperture priority or shutter priority 、white balance ect, while everybody took part in actively and asked for the instructor's help for problems he/she had encountered before in photography.
