If I think about it from the original photo question, the source doesn't have noise. The source is the light I am trying to capture with my sensor, and the noise comes from the electronics in the camera, starting with the sensor.

Before amplification, both had the same amount of noise. Isn't that what you said when you answered "True" to my statement that the signal was masking the noise?
