How so nfpotter?

Perhaps I'm missing something - if I am I apologise for giving wrong info but if I wish to brighten the image I'm recording - those three things will surely do it?

What we have here is a failure to communicate - with semantics, that is.  The point I think some people are trying to convey is that the amount of ambient light in the environment does not change (unless, for example, the sun comes out from behind a dark cloud).  Settings in the camera can, however, effect how much of that available light is brought onto the sensor.  Think of the example where you have the shades drawn in a room during the day.  The interior is dark, and the light in the room can be adjusted by opening the shade.  The available light (outside) never changes, but the brightness of the room can change by letting more of it in.  However, if you've opened the shades to a point where so all the available light is brought in -- opening them further does not result in more light -- and in the OP's case here, perhaps all the available light has been brought into the sensor, so increasing the ISO only increase the noise but has no effect on the brightness of the picture.
