I have an iBook and a Sony camera which takes mpegs. Today some were made of my g'daughter's Baptism and they are way too dark. Is there any way at all to lighten them up? I use QuickTime to play them and the stills I can run thru PhotoShop Elements and lighten, but I can't seem to find a way to lighten them in QT. Any helpful hints out there? TIA, Pat
