Man you have to read the whole thing. The total light reaching the lens from that subject is less, but that light is now spread over a smaller section of the sensor. So the light intensity on the sensor remains the same and thus the total exposure remains the same. There - I have now said the same thing around 5 times in 5 different ways Please refer to my white square in the black wall example above, and tell me what problem do you find in that description?
