Recently i purchased a new monitor which i calibrated with what i thought was success .However i have mailed a few images to a friend (also has a calibrated monitor )prior to posting on this forum for an opinion and he thought they were very pale so..... after recalibrating my new screen and installing the icc profiles where required,i sent the images again (still pale was the reply ).
So we processed an image on his computer,screen etc and saved to a card which i then viewed on my computer the result was a very dark image .!
Has anyone else experienced this or can anyone explain it .we have calibated our screens with the same equipment under the same conditions .
Check if you have any ecoview-type screen dimming technology built in - many of the Eizo range have it and it alters screen brightness automatically to suit the ambient brightness. If this is not switched off you could get in a bit of a pickle if you've got wildly varying lighting in your room.
Sounds like you're just profiling the monitors, not calibrating. Profiling will just do the colour matching, not necessarily the brightness.
For calibration you should also be setting the monitor brightness in candela/lumens and using the calibration device/puck to measure the brightness. Profiling will just do the colour matching, not necessarily the brightness.
Check the instruction manuals to see if there are different options available...

Cheers guys ,we have both used the Colorvision spyder 2 and relevant software ,also followed all the instructions (although some contradict themselves).
I see his images as quite dark and he says mine are light ,yet when either of us post here noone suggests could be lighter/darker
just a thought ... you are both working to a display gamma of 2.2 aren't you? Both LCD?

Spyder 2 is a bit old-hat now, and I was at a clients the other day trying to sort out the mess a Spyder 3 auto option had made of things.
I used to use the Spyder 2 on CRT monitors, but since I switched to flat panels personally I find the EyeOne2 Display gives me better results.
Correct colour calibration needs to be done manually where you use the screens OSD options to set a custom colour temp of 6500K using the individual RGB slider controls in the monitor OSD menu.
If your monitor is showing the correct contrast range - which a manual calibration should check, then the most important values to set are the white point (which is contrary to what others say) and the colour temp.
If you set your calibrator to manually check that the Gamma is 2.2, the temp is 6500K (not a monitor preset - manually adjusted to such) and a luminance of around 110-112 cdm2 then you will be fine and your images will look as you intended on another calibrated monitor.
Lots of forum members DON'T calibrate their monitors and they are happy - it's not a "do this or die" necessity, but if I'm not seeing what you see when you process an image then one of us has a problem - and it ain't me
