>You can't take photos of the Earth if you are already on it anyway.
No.

>We use Neptune as a pranic mirror (frequency 5,873)
That makes absolutely no sense. Photos of Earth exist, there's no need to fake it.

>pictures of earth from space are fake as hell because water isn't blue
https://en.wikipedia.org/wiki/Water#Color_and_appearance
>The apparent color of natural bodies of water (and swimming pools) is often determined more by dissolved and suspended solids, or by reflection of the sky, than by water itself.
>Through a thickness of 10 meters (33 ft) or more, however, the intrinsic color of water (or ice) is visibly turquoise (greenish-blue).

>Why is the sky black?
Because most of it is empty space, so there's not much to see.

>How do you know if the surface of Earth is convex or concave?
There's many reasons as to why, but here's a simple reason to how we know. See picture.

Part of it is that there's no atmosphere in space to scatter some light, resulting in harsher and less "real looking" shadows. Look at a CGI render without shadow softening and then with softening and you'll see what I mean.

>The ISS pics and the recent Starliner footage don’t look this way.
Different cameras and exposure settings can lessen the effects of harsher shadows. Also, some images for public display could be edited to look better.
