no worries Kuz - i think you are using GIMP? I'm not booted into linux on this machine at the moment (where I have GIMP on this machine) but from memory, it is -> Color Tab -> levels - then you will have to select the channels from a drop down box (perhaps it is called Channel); one at a time (red green and blue ) and move the left most square towards the right, just before the front of the histogram curve.
Changing levels doesn't have to be heavy on the system -you can turn the preview option off in GIMP so it will load the changes after you move the black point.
Hope that helps.
cheers
