A cinematographer is one photographing with a motion picture camera (the art and science of which is known as cinematography). The title is generally equivalent to director of photography (DP), used to designate a chief over the camera and lighting crews working on a film, responsible for achieving artistic and technical decisions related to the image.-WikipediaBasically a cinematographer is the person behind the actual camera and making sure everything is lit right (with electrical lights or through natural lighting using bounce cards (reflectors) Pictured below)
From cinematographer Dustin Farrell, below is some amazing time lapse photography.
A year's compilation of my time lapse work. All shot on the Canon 5D2 and processed in Adobe After Effects. The majority of the shots are in my beautiful home state of Arizona. Goblin Valley State Park and Natural Bridges National Monument in Utah also make an appearance. Most of the motion control for this video was done with the Stage Zero Dolly by Dynamic Perception. In addition to the Stage Zero, I also used a three axis motion controlled CamTram.-Dustin FarrellCheck out his work below.
