Thanks! That got it.
Curious: I'm using v2.70, but I could not find the Hue/Saturation settings on the menu bar. I would expect it to appear under the Effe&cts menu item, but nothing there seems to correspond to Hue or Saturation.
How can I take an image and lighten (or darken) the whole thing?
I typically use this setting in image editors when a photo has been taken where there was too little light for a good exposure. If I lighten the image a little, a bad picture can come out to looking incredible.
Thanks for your help.
