Rob: I suggest you go for a better grade of Champagne. While lookign at Michael's image, drink glass after glass until the horizon looks sufficiently level to you.
Ah Eric, here in Spain they lost the Champagne wars and only lower case(s) will do; not just any old sparkler will pass muster anymore. Perhaps itīs all the fault of Napoleon who is repute to have said of it: In victory you deserve it; in defeat you need it. It is not reported whether Napoleon was given to photography, though, and there is danger in following him too far along the silver path.
