Over the last decade, the increased use of digital cameras, higher-resolution video taps and/or on-camera monitors have provided focus pullers with additional tools to help maintain proper focus.

Those who want to understand the industry must learn about gaffers and juicers, key grips and wranglers, greensmen and gobos, inky dinks and skypans, not to mention focus pullers, Foley men and line producers.

These allowed the production team to work in very tight spaces, using minimal lighting, while also offering a very shallow depth of field putting the backgrounds out of focus, and making the work very challenging for the focus pullers.

In setups where the focus puller cannot touch the camera, such as on steadicam or crane shots, he or she will use a remote follow focus system, though some focus pullers prefer using a remote system at all times.
