I figured you would have used some technique to ensure a level horizon. Must be all those wonderful lines that's causing my pee brain to see it as tilted. Or, maybe, I'm just tilting my head!Well I did use a spirit level on the camera, could be an optical illusion, or, tired old eyes
It's not from money, maybe the Organ donor card tips the balanceI don't know that Ian's wallet was so heavy.
It's a nit picking discussion, I would most likely leave as is as Martin's done. It's the way lenses render perspective and something we see and capture with LF cameras.The line is from PS guide, the horizon goes straight then starts to drop at the left side, that's because that far side is not on the same line, the reservoir is turning and coming back on itself, if that makes sense.
