When I am trying to get a scan of my artwork just right, I notice that the richness of the color, the contrast/brightness, etc. depends on what angle I have my laptop screen at.  I’ve been working with photos in photoshop for YEARS and have not pondered this question much.  I HAVE thought about it, but there just seemed to be a natural place for the screen to be.  But for some reason w/ the drawings it’s bothering me a lot more.  I suppose this is also an issue with regular flat-panel monitors.  And also crt monitors that are set to real bright or real dark.  Heh, back around 2000, while looking at my online photos from a computer that was not at home, I noticed that all my photos online were over-brightened.  Turns out I forgot that my CRT monitor at home was turned way down, the brightness, so I had been overbrightening my photos to compensate for that and not realizing it. 

So anyway, I don’t know why, but now that I’m dealing w/ scanned artwork, it seems that the image changes more when you move the angle of the screen just a little, whereas it’s not that drastic w/ photos.

Here’s an experiment I did- I took photos of the screen as I changed the angle of the screen and nothing else:

I know you can get monitor calibration spiders and such, but I am have spent too much money on stuff lately and am just not going to go there right now. 

Idunno.  It just seems that with scanned artwork, there is more of a visible change with a small angle change in the screen.  One of my drawings will need just a little tweak of brightness and I don’t know whether to adjust it in photoshop or move my screen.

I know, everyone sees different things because of monitor types, monitor settings, monitor calibration, system (macs see color differently than PCs!) **, and more.  I need to just go to bed, LOL.
