Lecture 12 - Practical Lighting Plans Part 2 Flashcards
What is left to consider when you have established which fixtures and filters etc you will be using?
Fixture mounting
Power requirements and cable runs
Other equipment to control and shape light
What is important to consider when mounting fixtures?
Limitations of equipment:
Maximum height - remember to allow space for air flow over the top
Bear in mind properties of the location:
Studios have a grid for rigging fixtures, can be powered or unpowered.
Can you hang the fixtures? This would provide control and free up floor space.
What should you do when you know all the details from the lighting plan?
Create a detailed list of all data so far
Once the list in compiled, what should we consider?
Power!
Total power required:
I=P/E (amperage =wattage/voltage)
Then consider how many power lines you need based on overall power needs
Will there be any issues with line loss?
VD= 2 x K x I x L/Cmil
Is it within the 5% safety limit?
What other equipment is needed?
Flags to control spill, C-stands to hold flags for floor lights, sand bags to secure C-stands and lighting stands, gobo arms to hold flag for grid lights, black wrap to control heat (if fixtures are close to ceiling)
How would shooting a scene on location be different?
Existing attributes - windows can be used for realism
Likely less floor space
Likely lower ceiling
Likely need to use stands rather than hanging fixtures
Likely lower power capacity or fewer power points
Ventilation is particularly important
What else do we need to know?
How much does the gear weigh? How many crew do we need to pack/unpack? Safety issues for rigging/deriving? Vehicle access and safety? Environment weather? Temperature? Noise? Neighbours?
