The moon is that big in real life. Its a common misconception that the moon is really far away, but it’s actually really close. The reality is that you can hop on a number 52 bus and be there in less than an hour.
The image is in no way edited or adjusted, and the moon definitely hasn’t been added in
I would get two photos, the photo of the moon itself, and the photo of the aircraft + background visible, then i use Picsart to combine both of them, i have a video on how to do them but sadly i can’t share videos here :(
