[QUOTE="Blade Canyon, post: 602612, member: 15302"] And they should look the same. The answer is in your post. The amount of light hitting the sensor is exactly the same in all three shots. Same shutter speed, same aperture. By adjusting the camera's ISO, all you're doing is telling the camera what the final shot should look like. If you take the RAW 1600 file and turn up exposure two stops in Lightroom, all you're doing is turning up the ISO to 6400, except you are doing that step in post processing. With the exact same light information as a picture shot at 6400 in camera, you should get the same result. Paul says he sees differences, but I suspect they have more to do with your auto noise reduction. J-See could explain it better. I did these exact same tests as you when he explained that he set his shutter speed and aperture where they had to be to catch birds in flight, then he did all of his ISO adjustment in post. [/QUOTE]
