well...if you just assign the aim profile, no pixels at all will change.
the conversion to adobergb (so the pixel are those, you see on your monitor), alters the pixels the first time.
it's mostly the second conversion revealing some noise.
thing is: i dont think this technique produces noise.
it's just - if you shot a very dark picture and not enough information is in the shadows and you lighten them, it's pretty natural to reveal(!) the noise, with which your camera tried to display the information in the dark
have a look at my pictures.
each one of them ran through at least 3 times AIM-conversion...and only the last one (shot pretty dark) shows ugly artifacts in the shadows i revealed.
(by the way - i always work in 16bit - this larger pixeldepth reduces the creation of noise pretty good)
