Let’s take a look at a common video lighting location challenge – too much contrast.
The kitchen has too much contrast to expose for shadow and highlight detail simultaneously. The dynamic range is beyond what the camera can handle. The top raincoat image is exposed correctly if the objective is to see detail in the shadow areas. As you can see from the small image at the left. This exposure setting renders the floor-cabinets in front of the rain coat light gray to almost white.
The rain coat image below is exposed to show detail in the highlight areas and out the window. We can see detail in the curtains, blue sky outside, but much of the interior is black. While this exposure setting is good for the curtains, you can see by looking at the small image to the left, that it renders the same floor-cabinets in front of the rain coat, dark gray to black. If this was a video shoot, we could either bring the interior lighting level up, or we could gel the windows, which would bring them down. The problem with the second choice is we would also lose some of the light coming into the kitchen, making our shadows even darker. So ultimately, if we wanted less contrast we would need to bring in lights and likely gel the windows.
As of recently, there is a third choice and it’s called HDR “high dynamic range.” This has been around a while in still photography, but it’s very new in video. HDR can give you the best of both worlds by combining images. You’ll notice in the HDR raincoat image below, both the shadows and the highlights are exposed for detail. I haven’t created HDR video, but I have heard of mixed results. It works great in photography.
If you’re working with a trained cinematographer, you don’t need to know how to fix this. It’s enough to understand the basic concept. You can rely on your cinematographer to handle the details.
As the director, you need to provide a clear vision regarding lighting design as it pertains to mood, style & tone. http://t.co/zswGUKMRwp

This means you’ll need to learn the vocabulary of the craft, as well as collect and share photos or screen grabs that inspire the feeling associated with the image in your mind. But, if you’re shooting and want your images to enhance the tone of your story, then it’s important to train your eye and learn the limitations of your gear. Producing yourself into an impossible lighting scenario; wastes time, hurts your film, costs you money and is incredibly frustrating for you and the entire cast and crew.
