Insurance – Liability, Shoot Insurance, and Riders/Binders
“Liability refers to your basic insurance package you must have to cover loss or damage to your equipment, and to protect your personnel.
Shoot insurance is a more costly type of insurance that will cover you in the event you need to reshoot a job.
Riders/Binders cover the additional insurance costs involved when you rent a very expensive piece of equipment, or want to shoot on a location where the owner wants to be named as additionally insured on your policy in case anything happens to their property.”
