Great article Rishi. All of the comments and your responses to many of them enhance the article. Looking forward to parts 2 and 3

The section on the effect of sensor size on noise only applies if the sensors have the same number of test tubes (pixels). With the same number of pixels, each individual pixel on the larger sensor receives more light. If the pixels are more or less the same size i.e. pixel pitch is similar then both sensors should have the same noise although the larger sensor will have a higher resolution (more pixels)

Using the example of two same size sensors, one having 24Mp and the other 12Mp, the 12Mp sensor should have less noise. Same as having two same size rectangles with one containing 100 test tubes and the second containing 50 test tubes of double diameter. The 50 test tubes would each have more water than the smaller test tubes although the total water captured by both rectangles would be about the same.

As for shooting to the right, this may depend on the sensor. The dp review of the Nikon D5500 observed that it has an ISO insensitive sensor. Check out section 9 in the review
