 * Time
 * The lines on the board-formed concrete in the entrance bunker for an artificial horizon. I estimate the horizon to be 175 pixels from the top of the photo, just below the nail where the white piece of plastic is hanging.
 * The camera lens is an inch below the eye level of the cameraman. The shadow of the camera is at about 435 pixels below the top of the photo. The shadow is thus 260 pixels below the horizon.
 * Wikipedia says the angle of view of a normal lens is about 43° diagonally. Let's say this camera has an angle of view of 44° horizontally and 33° vertically. The image is 900 pixels high so 260 pixels equals 9,533 degrees.
 * The table published by Postol gives a sun angle of 8.40° at 7 am and 15.60° at 7:30 am.
 * Whatever the lens is, the time is about 7:05 am.
 * Note, that there is a sun dial on the back wall of the left hand exit.


 * Whatever the time is, the bodies would have to have been collected and loaded at some other location (after the trucks were procured) and then driven perhaps 3 km and then unloaded and sprayed with water.
 * I can't see any scenario where the initial gassing would have been less than 30 minutes before this scene

Later estimate: I ignored pixels and lens angles and just tried to read solar angles roughly for a range. Seeing how they line up, I would be confident to say it's probably about 8:15-8:30, maybe 15-20 min. earlier or later. But that doesn't even come close to include the times you're proposing. So ... whaddya think? --Caustic Logic (talk) 10:30, 26 April 2017 (UTC) (by the way, I'm using the NOAA solar calculator) --Caustic Logic (talk) 10:47, 26 April 2017 (UTC)
 * Azimuth: Sunlight is roughly down the side of the angled truck in the center, parked less than 45 degrees (wide 20-35 deg range) relative to the back (right-hand) wall, which runs app. 75 degrees on the compass (the main building does anyway). That gives a wide azimuth range of app. 95-110 deg = app. 7:45 - 9:15, weighted early I think, so a good estimate is 8:20 +/- 25 min.
 * Elevation: Estimating shadow length to height ratio, eyeballed, I think the shadows are only about 2-3x the person's height.
 * 2x body height = 26 deg = 8:28,
 * 2.2x = 22° = 8:08 am,
 * 2.5x = 20.5° = 8:01
 * 3x = 18° = 7:48
 * 4x = 14° = 7:28

Correction: Those measures were both quite rough and their lining up didn't mean much. I took a look at the distant structure with the arrow on its back wall. The walls have a height of 29 concrete molding slats, with 12 of those above the arrow (from close-up views). Here the shadow should cover about 7 of those slats. IF the structures depth (to that back wall) is the same as height (seems about the same), the shadow of the roof edge runs 29 units back vs. 7 down. That yields only 13 degrees elevation, for a time of 7:23 am (or so). Shadows will be 4.14 x height, azimuth is only 92. - that could be. I already decided I was reading short. --Caustic Logic (talk) 05:38, 30 April 2017 (UTC) A few minutes earlier. Note the position of the shadow in the "sun dial" entrance. The white plastic has been moved.
 * Other versions
 * Using the same method above on the "7 am photo" says the shadow runs down a bit under 6 slats, so elevation around 10-11 deg, time around 7:10-7:13 +/- minus whatever, when shadows would be about 5x body height, and azimuth about 90. --Caustic Logic (talk) 05:38, 30 April 2017 (UTC)
