James,
1) Just curious -- How did you go about showing that?
2) If Darnell was changing lenses in Towner, could said action while running, and at a distance look similar to windin' 'er up?
3) Do you think the "clips" in Denis' recent youtube video "Darnell Film Compilation, April 18, 2019" are in the correct sequence, particularly "Parking Lot" then "Cop at the Fence/Crowd at the Base of the Grassy Knoll" then "Sitzman/Wiseman" then "Jacob/Holt/Simmons Stepping Down From The Pergola Patio" then "Jacob/Holt/Simmons Walking On The Grass Towards The TSBD"?

Thomas,
1)
All of the scenes, except for the rail yard/parking area, were created and compared in my 3D model, in which I tweaked various camera locations while varying lens focal length. The Sitzman and Team JHS scenes were particularly useful as they both contained Pergola cutouts in the background that assisted in placing both the subjects, background, and camera distances. I can post those scene recreations if you like.
2)
Sure, with the video resolution we have of that Towner film he could be rotating the lens turret, winding the camera spring, or just holding the camera while jogging. The point I was wanting to make was that per (1) above the lens was not changed from Sitzman to JHS scenes. If he was playing Russian Roulette with the turret then by chance the same lens ended up in the same place

.
3)
The only scene
sequences I am 100% confident are the scenes as Darnell first strolls down Elm and the Sitzman/JHS scenes. The Sitzman/JHS dots are connected by Darnell in the Tina Towner film. After crossing Elm I'm not positive about his path and continue to try to figure it out.
