Bobby Shafto | Channel Buoy Observation No. 7 @bobshafto | Uploaded July 2021 | Updated October 2024, 2 hours ago.
USNS Henry J. Kaiser (T-AO-187) on approach to San Diego Bay, July 27th, 2021
In this segment, the camera was set at 15 ft about where the water is on a +3 tide. But the tide was actually +4, meaning the camera was only 14 ft above the level of the water. The channel buoys float on the water and are 15 ft tall, so that camera was 1 ft lower than the tops of the buoys.
Raw video. No commentary or analysis. Buoy's still appear to drop vertically with distance despite camera positioned at same height above the water.
Also, ship's angular size increases as perspective dictates. But it also rises relative to horizontal, which perspective doesn't dictate.
Angular size is not angular inclination/declination.
