This photograph has been undisputed since its presentation in a Fort Worth chat forum in June of '09.
Why would it be disputed (from a FE/RE point of view)?
It's a panoramic shot in an architecture forum.
If anything would be discussed it would likely be details of buildings, where it was taken from (actually a point of the linked discussion), which type camera was used ...
It is a photo of Dallas and Fort Worth in the same shot...30 miles apart....on the same FLAT plane.
Given that the difference in elevation is over 200 ft. (Dallas approx. 430 ft, Fort Worth approx. 650 ft, elevation of camera unknown), how is this a flat plane?
Obviously in a relatively small area, local features of terrain are more significant then "global" (FE or RE) characteristics.
As pointed out by others, 30 miles isn't a large distance compared to the size of the world.
Anybody care to dispute, or disprove, the photo?
Let me point you to the TFES FAQ:
https://wiki.tfes.org/Flat_Earth_-_Frequently_Asked_Questions#There_are_many_pictures_on_the_Internet_and_in_other_media_depicting_the_Earth_as_being_round._Why_do_these_not_disprove_the_Flat_Earth_Theory.3FIt points out that - for several reasons - TFES "do not lend much credibility to photographic evidence."
Also, I know some professional photographers and it's really amazing what different effects/impressions they can create by means of perspective, choice of lens, settings (aperture, shutter speed, ...), filters, ...
This pictures may very well be authentic ... but by itself, it doesn't prove or dispute anything.
Based on this photograph I wouldn't decide either way.
