Video sped up (sim. time-lapse) and desaturated for better contrast.

Watch where the level line align on the hull of the ship. The red cross on the hull provides a good reference. The camera/transit location is 20 ft above MLLW, and tide was +2 ft rising to +3 during the sequence, which put the camera height above water about 17-18 ft during the ship's approach.

$Draft Template for Recent Anacapa Island Videos (See Description) This is a rough draft of an idea for comparing globe vs flat prediction against actual observations being published on the Pablosdog channel. These are crudely edited on an iPhone using InShot editing app. Its just a concept video, and utilizes simulated renderings of the scene produced by Heath Carmody. (The magenta notations are from his source video and are not applicable for this presentation.) The flat earth communitys contrary argument to a globe earth often focuses on what should be visible for a globe earth of a specific radius (3959 miles). When we observer more than we should, its suggested to be evidence against a globe earth. Flat earth proponents rarely, if ever, examine what an observation would look like - should be - if earth is flat. But as Ill often say, not a globe is not the same as a confirmation of flat. An observation that appears to match a globe earth of radius 5000 miles or even 10000 miles is still not flat. What this template for overlaying comparison real world video captures of this scene can do is place a globe prediction and a flat prediction, without any adjustment for atmospheric/atmoplanar refraction on top of each other for comparison, and against which we can gauge whether the actual observation is closer to a geometric globe or geometric flat earth. The first question I have in attempting this is how to anchor the images. Vertical angles relative to the camera/eye are an essential element of the globe/flat comparison, but there are typically no visual cues or measurements provided as to where eye level is in an observation. We can predict where that 0 degree vertical angle would be for geometric flat and globe simulated renderings, and anchor the simulation images on that line. But how do we know where eye level is in images taken by Pablosdog? In this draft, Ive taken a still image from his February 12th video and aligned it with where a globe earth with standard refraction would align eye level against the island. Is that biasing? If the flat earth community has a better suggestion, Im all ears. The apparent horizon is a poor reference since it is universally agreed that it is variable and its vertical location is influenced by distorting effects like mirage. Whats needed is some mutually agreed upon method of establishing where eye level is in a field of view. Does the flat earth community have any ideas?$
