Business Sectors (Suites): Camera
Developed by: ScreenSkills
Approved on: 29 Mar 2020


​This standard is about setting and monitoring camera and lens parameters during shoots. This can apply to digital or film cameras.  This could apply to any type of production including feature films, TV dramas, commercials, documentaries, sports coverage, outside broadcast and live or stage events. This could apply on a multi or single camera shoot. 

This includes selecting and fitting filters, setting and adjusting camera and lens parameters, suggesting solutions when settings conflict, monitoring the effect of light sources, monitoring camera operation and resolving problems.

This standard is relevant to those working as 1st Assistants or Focus pullers.

Performance criteria

You must be able to:

  1. ​agree production requirements related to camera settings with appropriate people
  2. select and fit filters that meet colour temperature and other production requirements
  3. set aperture, camera speed, frequency, colour temperature, shutter angle and ISO to meet production requirements for shots
  4. use settings that take account of combined filter factors
  5. set required focal lengths for any zoom lenses in line with production requirements
  6. suggest viable solutions when you identify any conflict between, or difficulties with, selected lenses and camera settings
  7. report any problems or restrictions regarding camera settings that you cannot resolve to relevant people
  8. take action to ensure that flicker frequencies of light sources do not affect shots
  9. monitor the operation of cameras throughout shoots
  10. make any required adjustments to camera and lens settings at appropriate times
  11. resolve any problems with cameras with minimal disruption to productions
  12. work in line with health and safety requirements

Knowledge and Understanding

You need to know and understand:

  1. ​key characteristics of current cameras, lenses and attachments and major obsolescent models
  2. how macro lenses perform
  3. the limitations of equipment when production requirements change
  4. software for framerate and the impact of framerate on camera memory
  5. camera handling techniques and the implications of damage to cameras
  6. the capabilities, limitations and effects produced by different types of currently available optical equipment including filter colour, colour temperature and other optical parameters
  7. aspects to consider when adjusting camera settings including the effect of camera formats and focal lengths on angle of view, how to analyse depth of field and focus splits, flange focal depths and their implications, how to assess zoom collimation and back focus and how circles of confusion affect image sharpness
  8. commonly occurring flickering light sources, when and how light source frequencies can cause flare in the lens and affect shutter angle windows and how mattes and flags can resolve this
  9. the relationship between frequency and shutter angle windows
  10. aspects of camera operation to monitor including battery levels and when to reload shot footage
  11. how to tactfully suggest solutions to any problems or restrictions
  12. the role of others involved and when to liaise with them including directors of photography, camera operators, directors and 2nd camera assistants
  13. any special requirements to ensure the safety and security of equipment when left unattended
