Heath Carmody | Distance Offset Optical Test #3 - All Ferry Passes @heathcarmody2867 | Uploaded October 2022 | Updated October 2024, 18 hours ago.
Super hazy afternoon but still had some good results and a nice gradual transition of the apparent geometry.
The ferry passes the close point of land (about 6 km) at a distance of about 10 km. Camera height about 3 feet but I'll provide an exact measurement soon.
I skipped results for test #2 for now, since I'm working on a video for that test which will give an angular size reference of the camera. This will allow for fairly accurate measurements to compare the difference from each model (flat, convex, concave).
Green line is approximate eye level relative to the camera. All temperature data is based on fairly inaccurate measurements and is just a rough indicator. Temperatures likely varied over the distance of the observation. Cameras offset by about 50 meters (I'll have an exact distance soon). I've done 5 tests now and the last 2 were from closer to 100 meters. Interesting results, but not sure how useful they will actually be in proving or evidencing anything. More work to do and more to come!
