In celebration, I give you the Triforce of Power.
(What happened was, the lens froze stuck out and the camera wouldn’t stay on for more than a couple seconds. It flashed “E18” at the corner of the screen during those seconds, so I googled “canon s400 e18,” and found about eight million people on various websites suggesting twisting the lens (plus a class-action suit).
Seeing as the thing is long out-of-warranty anyway, I went ahead and twisted the lens. And it snapped menacingly and I nearly had a heart attack, but it’s okay again now. So, yay.)
