Look at all that curve in the "After" photo. What are you trying to say? That a picture, or even a person, could misrepresent reality?
Your picture is lacking context. Can you use a telephoto lens to zoom in on a ship that has partially gone over the horizon, and bring it back? Or the sun?
Can I use a telephoto lens to zoom in on a ship that has partially gone over the horizon and bring it back? Yeah, I think I can
Brilliant, you've demonstrated that when you zoom back from long telephoto to wide-angle you make it too small to see!
But once something has really disappeared behind the horizon, it stays hidden.
Any more magic up your sleeve?
Are you kidding? That boat is to far away to see with the naked eye! Haven't you ever used the zoom on a camera?
You claim "That boat is too far away to see with the naked eye! ", but that is not at all proven.
Look at the camera specifications,
"Nikon Australia - COOLPIX P900 - Take ultra high-power zoom to the next level with the new 16.1-megapixel P900 and get closer to your subjects with 83x optical zoom (24mm -2000mm equivalent in 35mm format)"
All it shows is that a 24 mm wide angle image, displayed on a computer display it does not seem to have the boat visible.
That is quite different to being "too far away to see with the naked eye". The naked eye has better resolution than that.
But, so what! The question in not
whether a boat "too far away to see with the naked eye" can be restored with a telescope, but
whether a boat that has apparently "disappeared behind the horizon" can be restored with a telescope.
That is a completely
different kettle of fish.
While on that video, there is no clear evidence of the height of the camera or the distance of the buoy and boat.
Without that information, and considering what I said above, that video tells us nothing at all, so as I said before:
Any more magic up your sleeve?
