The results of this lighting test showed that as the light source moved further away from all three cards, their values became closer to one another. When the light was closer to the cards, there was a bigger difference between the value of the three cards (the closest one to the light being the brightest and the furthest away card being the darkest).

2.5 sec f/10 @ iso160

BLACK card: approx. 3 ft from light (1 ft from camera)

GREY card: approx. 6 ft from light

WHITE card: approx. 18ft from light

The results of this lighting test showed just how much of a difference the distance of a light source to an object will change the brightness/value of the object.
