Egg,
I am comparing George's photo (B) with Grable's photo (C). As time goes by, the shadows on the ATT building shift to the left (towards South, towards the WTC).
Since the Naudets video was (allegedly) created earlier during the day, you'd expect the Naudet shadows more on the right. Not the case. Just the opposite.
If the 20 foot shadow on the Tribeca Grand Hotel were real, you'd expect the 20 foot shadow shift to the left (towards South, towards the WTC) as time goes by. Not the case. Both George's photo and Grable's video do not reflect this expectation being correct.
Naudets (A) -- ------ 8:46 am 9/11/2001 (?)
George Weld (B) ---- 9:03 am 9/11/2001
Grable (C) ---------- 8:55 am 9/14/2008
