Kann mir jemand helfen, zu verstehen, warum die Oberfläche in einem Foto konvex ist und im nächsten konkav? Meine erste Annahme ist, dass die Fotos aus zwei völlig unterschiedlichen Ansichten aufgenommen werden, aber die Erde ist in beiden Schüssen am Himmel vorhanden. Beide Körper sind in Bewegung, daher nehme ich an, dass eine andere Sichtweise zu einer anderen Zeit auch mit der Erde aussehen könnte. Ist das auch ein Spiegelbild der Erde am Ende des zweiten Bildes? Ich würde gerne klarstellen, was wir hier sehen. Bilder von https://www.flickr.com/photos/fireflyspace/albums/72177720313239766/

Different cameras. One on top is fish eyed it seems.
Different camera lenses, and positions. The second shot where the horizon is more flat appears to be a wide angled lens. The first image has a lens that isn’t quite fish eye, but has a very similar shape causing the horizon’s curvature to be more pronounced.
On that first image – where is the light source coming from ? The shadows on the right rock suggest the light is from the right, yet we see the shadow of the lander suggesting light behind it. Two light sources?
She looks really lonely 🥺! She needs a friend!
Long story short: they’re not using [rectilinear lenses.](https://en.wikipedia.org/wiki/Rectilinear_lens) Thus straight lines beyond the center axes appear curved. The effect is known as [barrel distortion.](https://en.wikipedia.org/wiki/Distortion_(optics)#Radial_distortion)
Wide angle lenses produce distortion. A horizon above centre will curve one way, and below centre will curve the other.
fake, just like in 69 their doin it again; FAKE.
Curvature depends ob how far away from the center a line is. Above the center line it will be convex, below concave. In the final image it may look like both are at same location due to cropping.
Surprisingly I hadn’t even heard about this thing until it actually landed on the moon. Really cool!
With a lens like this, if the camera is positioned so the horizon is above the center line it will follow a curve up at the edges, and if it’s slightly below it will curve down. And a vertical line on the left will bow out to the left in the middle, while the opposite happens at the right. That’s why photos of buildings with columns often have that effect.
You can see this even with a horizontally-oriented phone camera zoomed out all the way, but especially with a fish-eye lens attached.
