When flat earthers question the authenticity of Soundly's photos based on distortion near the surface or fakery by Soundly, it may be useful to point out that distant mountains, buildings, and ships, drop down in elevation by the same amounts as Soundly's bridges at equal distances, even though the mountains are far above the distortion near the water surface. And flat earthers can likely verify this somewhere much closer to their home, though they may need to know trigonometry and have a theodolite or water level. Even if they come up with some other excuse to maintain their belief, it may be helpful if they can realize that Soundly's photos are not fakes or freaks, but show drops that are consistent with and readily verifiable in many other places.
