So, you pick the globe off your desk and alter it.
No.
I took 3 pictures of it and didn't alter any of them. OK, I cropped them. And I resized them so they weren't 3000 pixels across.
But that isn't altering them in the way you are claiming NASA alter images.
There are no filters, I haven't adjusted anything about the images - brightness or contrast or anything.
Those pictures are as I took them.
Do they all look the same? Does Africa look the same size with respect to the globe?
No, it doesn't. And that's the sort of inconsistency that FE people often jump on.
"Aha!", they say, "That shows that these images are faked and they're not even done consistently."
But actually it's as simple as this - if you take two pictures of a globe - one from fairly close and the other zoomed in from far away - then the results will look different. Landmasses will look like they're different shapes or sizes. Not because of images being altered, simply because of geometry. The first two pictures prove that.
The 3rd image was taken simply to demonstrate that if you change the camera settings then the colouring looks different. That should be fairly obvious but it's another thing that FE people dishonestly use as "proof" that the images are faked.
The basic FE argument is "if these are really all pictures of the globe then why don't they all look the same? The fact they don't proves they're all fake".
I've just driven a coach and horses through that argument. Pictures of the same object taken from different angles or distances or with different camera settings don't all look the same. That does not mean they are not genuinely images of the same object.
