Question Video Comparing 1 vs 2 lights

[Diggie]

Hello - looking to see if anyone has or seen any videos that directly show the same dive/scene but comparing using single vs double light? Just trying to really see the difference in the same setting. Thanks in advance.

If you are asking for the diff between using a single light source vs using 2 lights, you can easily recreate it using two flashlights.

The point of having two lights is to have them pointed from two different directions so that they eliminate/reduce the shadow that each light alone generates. You could have the lights each at 45 degree angle from the object. One light alone would result in a shadow behind the object. By shining a second light from 45 degrees to other side of the object would result in lighting up the shadow area thrown by light #1. It eliminates the shadow and more evenly lights the entire scene.

I understand the impact above water, it was more of not being able to visualize it underwater. Is it pretty much the same or is the impact on color in the shadows better because of the multiple lights. It’s more the color impact under water vs the full effects of multiple lights I’m struggling to visualize. Thanks.
