    waltis curve simulator.

    Walter Bislins has created a very useful tool for visualizing what things should look like from certain positions, and with certain camera settings, on the Globe Earth, or on a hypothetical Flat Earth.

    The Simulator includes recreations of classic and modern experiments and observations including the Bedford Level, the Pontchartrain Power Lines and Causeway, and the Chicago Skyline. You can stop the simulation at any point, and examine the scene and the settings used. Here's a (non-interactive) animation of the Bedford Level experiment.

    I'd encourage anyone interested in the topic to play around with the various settings and watch all five demos.

    I've used this simulator for high altitude footage I found on Reddit/Youtube, which according to the author was taken at an altitude of 115,000feet/35km with a Canon Powershot SD880 set to 35mm film equivalent of f=40mm.
    I'm not really good with photoshop and had to do it on my smartphone, so it doesn't look as good as the examples made by Walter. Anyway, here's what I got: videoto_2017.08.23_14.26.56.
