Photographer, Motion Designer, Art Director, It doesn't matter; reading light is fun as hell and i’m positive you will learn something from it if you are not alreadY.
What we have so far in our equation are the basics. We have reflection source, light direction, and stage setup. however, To fully develop the entire formula we need to dive a little deeper to find out our light intensity and distance. To do that, let’s look at our shadows. You might first wonder why we don’t just look at our reflections to see our light intensity. The issue with that method is that the reflection intensity can also change according to the subject’s (in this case our “soda orb”) specular intensity, which can change depending on what materials you are dealing with. So, what do you see our shadows doing? We see that the direction of our subjects shadow trails off to the left of the scene but it also has a really soft feather or diffusion along what would be the edges of our shadow. But what causes the sharpness or softness of shadows? The distance and sizes of our light sources! For example, on a sunny day, you will likely see sharp, deeper shadows on the ground being cast from objects because of the brightness of our sun and the distance from the light source to our objects creating the shadows. But, when looking at objects outside during a cloudy day, the light from the sun is being diffused by the clouds, which now allows the clouds to be our main light source. The equation is then reset and now we have a large light source closer to our objects creating softer shadows. Since we see softer shadows on our stage and with the information we see in our reflections, we can safely say that our light sources are diffused, and relatively close to the “soda orb”. So let’s recap. We have 1. A curved stage 2. A large size light source relative to our object. 3. another large light source (about 3/4th the size of the main light source) to the left. That’s about it! So, let’s re-create this thing!
