Much of Video and Photography is about light. Learning how to use light is essential to developing natural looking photos and video. That is what an amazing Cinematographer does. Direct intense light can be harsh which will intensify the contrast between light and shadows and can be very unflattering. Anyone with wrinkles on their face usually does not appreciate visual media with harsh light.
When working with diffused light, contrast is usually much lower and the light is more flattering. Here are some suggestions. If you find some cover, shade can act as a great diffuser.
Recently I was on a commercial shoot in a room I was unable to scout and part of the production was shooting interviews and there was little time to set up production lights. I was able to locate a large window with a diffused shade over it with plenty of sunlight hitting it.
Here are a few screenshots from the video.
After color balancing my Canon XF300 to interpret all the light temperatures in the room, I was able to use the diffused window for a key light and the existing room lights for fill and back lighting. This is a great example of how to use existing light sources to create your Cinematography. Hey, the plant was an added blessing!
So, next time you are you documenting an event, do a quick search for some natural diffused light that might be nearby. If your Mom or Grandma has wrinkles, they will love you!
