I stitched together this photo for fun... found out that of course its a bit complicated to do that as waves are crashing in, but I think it looks *relatively* seamless. I'm sure you can see where the waves just don't look right though. Main question- you think the curvature of the ocean here is due to the actual shape- ie the curvature of the earth, or just an effect from my lens? I figure it couldn't be the lens, because why would it be over multiple exposures (there are 16) like this? But I'd also be surprised if it was the earth... thoughts?
