One thing that make me a bit confused about using LCD monitors and I'm not sure I'm doing the right thing. 

Depending on the position we look at, an image will appear darker or lighter, brighter or paler.  I have learnt that for ergonomic reasons we should have our eyes aligned to the top portion of the screen.  Is that the good thing when it comes to photo edition?

Maybe someone using a calibrator can give some interesting feedback.  The only calibration I do is that using an image with a gradation between black and white in which we have to be able to distinguish all the squares.

I also have an LCD monitor and depending on the angle of view, the lightness/darkness of the image will vary.

I would guess that a calibration tool will work at exactly a 90 degree angle to the monitor.  So, we should be looking at the monitor in the same way.

I used to use a laptop and was always bobbing my head up and down to try and figure out where the 'right' place to view the screen was.... pretty impossible really. 

  This is what I do.  I am sometimes finishing off a picture and after i move my head, realise I have over saturated the photo as due to the angle, it seemed a lot darker.

LCD's are getting better so shouldn't change with an angle.
