I can go into the raw file converter and change it after the fact, by
altering the ISO setting? I dont think so, not and get a good print.
It's important to separate what happens before the sensor records the
image and after the sensor records the image. The amount of light hitting
the sensor is controlled before the image is taken, by ISO, aperture, and
shutter speed. Everything else, including white balance and
contrast/sharpness/hue settings happen afterwards. Anything that is
changed afterwards is completely controllable regardless of the settings
in the camera (for a RAW image), which is why you are wrong about the WB.
However, there is generally more exposure latitude with a RAW image than a
camera-produced jpg.
