Photo-Math-Unicorns : Most PERFECT Example: 100% True Math & 100% Wrong Conclusion
Statement: Correct Math, WRONG Conclusions:
OK, both cameras are directed at the same spot on an evenly lit white wall/backdrop that covers (more than) the field of view. Now the full-frame (FF = 36mm*24mm = 864mm², for Nikon fans: FX) obviously gathers more light, because it has larger sensor area
whereas the crop sensor (for Nikon APS-C: DX = 36mm/1.5*24mm/1.5 = 864mm²/1.5² = 864mm²/2.25 = 384mm²,
for Canon APS-C: 36mm/1.6*24mm/1.6 = 864mm²/1.6² = 864mm²/2.56 = 337½mm²) has none.
Imagine for that sake a single camera with a crop sensor: it gathers a certain amount of light. Now extend it with the frame around it that makes up the difference to the full-frame sensor. Of course this new, bigger sensor gathers more of the light than around the previous, smaller sensor additionally. This is for Nikon 1.5²=2.25x (=125%) more, for Canon 1.6²=2.56x (=156%) more light gathered on the FF over the whole sensor.
