Anyone dabble in the physics of overlapping light waves of varying intensity? Is this just a perception issue?
No, but if i had to guess, I’d say it’ s a “human eye adjusting to available light” issue. Any brighter lit area will not only draw your attention, your eye will adjust to the available light (iris dilates in the dark, contracts in the light) and surrounding areas will be darker. I mean, they won’t actually be darker if you put a light-meter on them, but they will be actually-for-real darker in terms of how much light from them enters your eye.
