Heath Carmody | 4K Refraction Time Lapse from Observation #10 @heathcarmody2867 | Uploaded May 2022 | Updated October 2024, 20 hours ago.
I still haven't been able to make another observation since #10, partly due to time restraints but mostly due to unseasonable weather. I still had some good footage from past observations so I'll be putting out a few more videos in the coming weeks.
This was from some time lapse captures over the course of about 3-4 hours. Same observation as my last few videos (including the 'black swan' one) but from a slightly different position, to get the 'waterfall building' in view.
Camera was at about 5 feet above the lake. Close land about 2.3 km, far land point at 11.7 km, and farthest hill about 22 km. I'll be analyzing this at some point because it is a good one to show how refraction was effecting things at higher altitudes than usual. These are also much wider angle views than I normally shoot.
There is some apparent camera/tripod movement, although the day was very calm and the tripod was never disturbed. Watching closely, much of the full frame movement does seem like it could be refraction that is slightly shifting the entire scene, except for the most immediate foreground.
A 'closest to globe' relationship of the visible water between 2.3 km and about 10 km can only be (somewhat) observed near the beginning of the sequence, with multiple inferior mirages present. There is a brief moment where it appears the least distorted and closest to flat (in my opinion) after which the weird concave/reflection/inferior mirage condition starts to develop. More on this in an upcoming live stream.
