User:Mer0026/Focus puller

A focus puller or first assistant camera (1st AC) is a member of a film crew's camera department whose primary responsibility is to keep the camera focused on whatever subject or action is being filmed. This is done by changing the lens' focal length in relation to the subject's position. The focus puller may also shift the focus from one subject to another within the frame. This is called a rack focus. Focus pulling is an advanced technique with little room for error. Sharp focus produces a realistic image, automatically draqing the viewer's attention. When done correctly, focus pulling goes mostly unnoticed by the audience.

Responsibilities
The focus puller works in tandem with the rest of the film crew to set up each shot and is responsible for maintaining or adjusting the focus while the camera is filming. A focus puller's responsibilities may vary on each shoot, however, in general they include:


 * Assembling the camera before a shoot
 * Assisting in operation of the camera and its accessories
 * Measuring distance to subjects before shooting
 * Measuring the depth of field
 * Pulling focus during individual shots
 * Cleaning and maintaining camera parts during shoot
 * Ensuring no camera parts are misplaced

These responsibilities may change depending on how large the crew is and the specific demands of the shots.
