Have you ever tried to take a picture without flash while standing in front of a window? Did you notice that the people you're trying to take a picture of look like dark shadows while the window looks completely normal? That's because the camera is focusing on the lightest object in the frame and that happens to be the window. Some don't realize that even though you can see perfectly fine in that room, when recording a video, the camera can't pick up the same view. This is why lighting is very important. If you're having trouble with ways to properly light tutorials we have a couple of easy and inexpensive ways to improve your setup!
The easiest and least expensive trick is recording with natural light! Make sure the light is directly hitting your face and not behind you. If you happen to have a window on one side of you, you can easily add more natural light on the opposite side without it costing a fortune. All you need is a large white presentation board. Place that presentation board on the opposite side of the window and make sure that it is angled towards your face. It acts as a "bounce card" and will bounce the light from the window and reflect it on the side of your face that isn't getting enough light.
If you need artificial light and are low on funds, painter lights with clamps are a great option. They can be placed wherever they can clamp on, are very lightweight, and run for about $7 a piece at your local hardware store! Make sure that you purchase daylight bulbs that have less of a yellow tone (soft white gives everything a golden glow that's pretty in real life, but looks yellow on camera) so that the white balance on your camera will be normal. Having two lamps on each side will properly light your face. Also, if the lights are too bright, which might be the case for daylight bulbs, you can use vellum to filter the light. Just tape some over the lamp and you're good to go!
