When I download jpegs from my D30 - Lexar 512MB compact flash card - onto my own computer (P4 , 2.4GHz , 512MB RAM ) ALL the shots look underexposed ie very dark.
When same pics downloaded onto either my laptop - Dell Inspiron 3800 - or my mates computer results are much lighter/better.
Is it perhaps the setup of my computer and if so what or ????????????
Thanks for any thoughts you have on this.

I had the same problem. In fact, I even digitally brightened/gamma corrected each image only to find out that I had washed them out because my monitor needed to be "gamma corrected".
if you have Photoshop/windows you can go to control panel and select "Adobe Gamma" and it will set a profile for your monitor. This is a subjective method, but it works for me for the time being. A far more accurate way is by using a spyder and accompying software. The "spider" plugs into a USB port and attaches or is held to the screen, and then the software beams different color/etc patterns to the spyder and then a profile for your system is created.
The one I am considering is the Spyder Vision Pro Suite by ColorVision.

It's not cheap at $429US, but, if you are serious about making what you see on the screen match the print, one of these professional packages is pretty much necessary.
you can find more info on the luminous landscape site at http://www.luminous-landscape.com/ click on tutorials then monitor profiling (or calibrating.. can't remember exactly but you'll definately know it when you see it)
You can also do an internet search on "monitor calibration" and find a ton of useful information.
creating a gamma profile with Adobe Gamma made a huge difference in image viewing on my PC. It's still not quite exact, but MUCH better than before. The Spyder will have to do the rest of the work when I can afford it.

Some of the other experts on this forum discuss this in more detail under the key words Color Management.
I have been trying to survive using David's PS Gamma approach. It worked fine with my old 17 in monitor, but upgraded to a 19 in anxd this new babie is bright. So I have "calibrate" with as low a level of brightness as I dared.
Today I bought refills for my Epson 880 and started printing a few 8 by 10's. Ouch! I never did get the match that I had in the past. When I converted the "mode" to Epson the print was too dark. When I went direct from "Mode RGB" the print was too light.
So I have to go back to the drawing board becasue my paper and ink cost an arm and a leg.
Good Luck !

If you have Photoshop, look in the Control Panel for Adobe Gamma (don't know, if it comes with Elements as well). This is a reasonable (and cheap) way a getting some kind of order into your monitor calibration.
