If you're on a budget, this is a great lighting kit to start with. Buy some FULL CTB gels with this kit to have the most flexibility when lighting.
When you get a bigger budget and want a lighting kit with more power and flexibility, go for something like this...http://www.bhphotovideo.com/c/product/752187-REG/Arri_571964P_Softbank_D...
•Wear Comfortable Shoes - (You'll be on your feet all day.)
•Note Pad and Pen - (You may need to make a run and write a list down)
•A Map or GPS of the area that you're filming at. - (When you make runs or need to get something for the set, you'll want to know where you are going.)
•Gloves - (To protect your hands from dirt, water, etc. You never know what someone will have you do.)
•A Multi-Tool - (These things are an essential on set.)
•Sharpie - (To label with.)
•Sunscreen & Bug Spray - (You never know where you will be filming and for how long.)
If you find yourself in the grip department:
•3 Prong Adapter
•Clothes pens - (C-47s) to hand to gaffer, or gel lights.
•A Cheap Circuit Tester
It also never hurts to purchase a slate.
If you're going to spend the money on a c100, then just get this when it comes out...
It can be pretty mobile when stripped down. It is a new BM product though, which will more than likely have some bugs here and there... but I feel like the features will allow more options for you in the future.
If you're talking about bare minimum...
*Camera (a DSLR is a great place to start)
*Prime Lens (35mm or 50mm)
*Multipurpose Audio Recorder w/ integrated mic (example: h4n or h6)
*Utilize Natural Light (this will teach you basics of lighting before you start to incorporate lighting kits)
It's about the end goal, technically people have made films with just an i-phone. The kit can be as basic as you want to make it... Essentially you don't need all the bells and whistles to create a fantastic film. A great story, acting, and editing will go a long way...
I use an H6 with NTG4+
The NTG4+ Shotgun Mic is usually on a boom stand that is close to subject but out of frame. I run an XLR from that boom stand to my H6 on another tripod that is next to my camera setup, so I can monitor levels while I'm filming.
If it's an interview, I'll use the shotgun setup, as well as incorporate a wireless lav to the mix.
