You aren’t wrong that a high altitude could cause an effect like that, but if that were the case, then neither of them should appear that large in the photo (and especially not that wide). And if it was taken from close enough that they should look that big, then the shape of the door should be warped more or the distance between the person and the door should look smaller. Basically, all of the proportions can’t exist together in the photo as they are; something would have to change, whether the distance from the person to the door, the shape/angle of the door, the height/angle of the person, etc… You can’t just compare the raw heights and say they’re the same without factoring in anything else.
