If you plan to shoot a film, you need to think about lighting and Noam Kroll of Premiumbeat published an article on how to light your film without a big budget. He writes that if you want to achieve beautiful results, you don't need just the right lights, but you need to learn how to shape and craft light. And he is perfectly right, because the same goes with shooting video - the hardware can help, but if you don't have the knowledge and talent, your videos won't look amazing. And so Noam reminds that lighting for a cinematic image involves many variables, but what matters the most is to achieve lighting that will speak to your audience. This is why you need to think how you can achieve your goal and what you want to tell with the scene - sometimes all you might need is a single light to illuminate your character, in a different situation you might want to use a three point lighting kit. But in general you need to remember that you don’t always need lots of lights to capture the mood of your scene and for every light that you add you will likely need a modifier or fill light to counteract spill/shadows from it.
Noam also suggests to use natural light:
"Utilizing natural or available light on cinematic productions is a fantastic idea, so long as it suits your story. It will not only allow you to free up space in your budget, but will also allow you move more quickly on set, as you don’t need to reposition lights in between every setup. (...) When possible, try shooting during magic hour or blue hour (an hour before sunset and an hour after sunset), as the quality of light at this time of day is naturally gorgeous and will allow you to use a minimal amount of reflectors/bounces, and still capture a soft quality of light on your talent."
Another nice tips is to use a China Ball to achieve soft light.
"China balls create an omni pattern of light, which works to provide soft light in all different directions. I really love these lights because of how versatile they are and how many different ways they can be used. For instance, they can be used as a key light source for your main talent, or alternatively you can use multiple balls to light an entire room if you wish."
