On the contrary, what I described is exactly what one would expect from a raw image obtained with an ISO-independent sensor.Thanks, it sounds like ISO less doesn't work hereThe faster shutter speed reduces the signal reaching the sensor (exposure). Increasing the image brightness by increasing the camera ISO setting or by brightening during postprocessing will increase noise proportionally... so you end up with a noisier image either way.why not use a low ISO and raise brightness in post processing though?Those are excellent as goals, however for most birds, the shutter speed must be far faster than what you use, and the ISO required for a bright image considerably higher. That's where a program such as DXO PL5/6 really makes a difference as the first-step processor, because it will much better at removing noise without blurring details than pretty much any of its competitors.While it's a good thing to know what a magic a program can do to reduce noise in and/or sharpen an image, I think the most ideal approach is to take a shot that's born noiseless (P Mode, ISO 100, -0.3EV) and sharp (absolutely no motion blur), as some of my finest shots demonstrated.
If not clear - these are from the raw file you made available, not one of my images.
