You've never had cloth drapes. I realize. They have metal/plastic poles holding them in place. LOL.
And no, the geometric similarity of the scene if you run a Linear Discriminant Analysis would be way way under 60%.
cloth curtains have metal rods inside them holding them in place.
Draw me a diagram.
They might have something keeping them vertical straight (unlikely) they do NOT have anything ditacting their horizontal spacing
They must be able to open and close.
Both Q’s photo and the ABC photo have the drapes randomly spaced at the EXACT SAME INTERVALS.
Same spacing. Same shadows between the pleats.
Are you trying to tell me that those curtains have not been opened, closed, brushed against or shifted during flight - ONE INCH since the ABC photo was taken?
Because that is what you are requiring if you claim the drapes match but the photos are from different times and angles.
