Be diligent with your casting.
Make sure your talent is prepped and comfortable being on camera. Let them know what they’ll be doing beforehand, and if they need to bring any specific wardrobe. If you’ll be working with kids or animals, make sure the parents/owners are prepped similarly. You may also need a set teacher/animal trainer.
Allow enough time in your shooting schedule.
Remember that time of day (for exterior shots) and lighting set-up time will affect your schedule. You’ll need to allow time between set-ups accordingly.
Have a solid shooting plan.
Shot listing beforehand with your production company will make it very clear what you need to capture on the day. The more pre-production you do, the smoother the shoot will go.
Don’t get caught in the rain.
Sometimes weather changes can throw a wrench in exterior shots. Have a back-up plan or a protective cover available. Fun note: rain is difficult to see on camera unless you light it. The things that are most obvious on screen are wet people and objects.
What’s for lunch?
Know who will be sourcing lunch on the shoot day (you or the production company), and what time you’ll take lunch. If you’re providing meals, make sure you check in with your production company ahead of time to accommodate any crew dietary restrictions.
Production days are more strenuous than days in the office.
If you’ll be on set with your crew, you may want to change some elements of your day-to-day workwear, like your shoes. Nothing is worse than a piece of heavy equipment stubbing an exposed toe or tripping over cables.
Pick a quiet location.
Background noise like construction, leaf blowers, or people typing can make post-production more time-consuming and costly. Sound people also like the ability to be able to turn off A/C during a take.
Know the parking situation.
Time is money, and the more time the crew takes to find parking, the less filming is happening. Communicate the plan for where they can load in equipment and park.
