You won't get the advertised battery life out of any laptop - doesn't matter what name it has or whether it has an apple on it that's starting to rot.
Sure you can from a MacBook Pro. It's been verified by many people, including AnandTech
. Apple advertises 8 hours and that's what you get, even a little more.
But NO laptop will get much more when used heavily as in Photo editing.
Photo editing isn't that taxing on batteries. You want to use a battery in a hurry, run any Flash animation. Flash junk is electric drain.
"Raw" is not an acronym, abbreviation, nor a proper noun; thus, it should not be in capital letters.
