i tried adjust the colors, brightness and contrast, etc.  how come the
test image has the same look even if a adjust settings to the extreme?
 it seems that the adjustments i do doesn't have any effect.

what is rendering intent?  i tried accessing the help menu and it
doesn't say much about rendering intent - 

- saturation
- perceptual
- relative colorimetric
- absolute colorimetric

i don't notice any difference in the test image each time i change the
rendering intent menu as well.

thanks!

david
