Heath Carmody | Concave Creeper (Observation #7 Refraction Effect Highlight) @heathcarmody2867 | Uploaded April 2023 | Updated October 2024, 18 hours ago.
From observation #7 a few weeks ago. I've only made one new observation since this one due to bad weather, but that should change soon.
The main song is called "Moving On" by Marika Schanz. I thought it was suitable in more than one way.
This is a short highlight from one of 3 cameras that were positioned at various heights for a long duration time lapse, all with close height references in frame the entire time. There is a fair bit of analysis work to do, but I think it will be very useful when presented with actual measured displacement over a 5 hour period and a 3 camera time synced view. I don't know why I didn't do this before. I plan to do this a few more times this year too.
This video highlights a particular 'refraction' effect that I don't really have a name for. Similar effects can occur fairly often on warm afternoons. The water appears extremely concave, like, strong downward refraction on (in?) a concave Earth size sphere concave. Of course, there is considerable compression as only the lowest 5-10 meters appear consistently displaced that much. I'll save the model comparisons for the longer videos though. No subtitles to distract from the real time and some sped up footage. If you want more info on this observation, check out most of my last 10 videos, or ask anything, or wait for the full analysis video that may be a while. Otherwise, just enjoy the effect without over analyzing it. And know that eye level is somewhere around or below the middle between the ring thing and the average 'horizon' appearance.
This effect seems to occur when the apparent horizon is well above eye level and the image seems 'slow' compared to other broad refraction/distortion effects. Wispy bands may start to appear and large vertical displacements can be quite localized. The clarity of the 'actual' water reflection is interesting at this height and distance. The water was very calm this day. Objects can appear in different places on the water surface without a distinguishable mirage effect. I've done a few other videos with this effect which I'll post in the comments soon.
