Electronic field production
Electronic field production (EFP) is a television industry term referring to a video production which takes place in the field, outside of a formal television studio, in a practical location, special venue or fitting environment. Zettl defines EFP as using "both ENG and studio techniques. From ENG it borrows its mobility and flexibility; from the studio it borrows its production care and quality control. EFP takes place on location and has to adapt to the location conditions... Good lighting and audio are always difficult to achieve in EFP, regardless of whether you are outdoors or indoors. Compared to ENG, in which you simply respond to a situation, EFP needs careful planning."
