The PNG Gamma Dilemma
"The PNG format allows applications to embed gamma information to correct for variations in brightness (gamma) on different platforms. This is great news for graphic designers who want their images to look good regardless of where they're viewed; but ironically, it's also one of the obstacles preventing more universal adoption of the PNG format for the Web."
