Woo, i am learning Adobe Premier Pro (road trip, photography)

Eclipse trip was lovely but exhausting. I've had to catch up on sleep. It was damp, so unpacking needed also drying time. I have most stuff up now, so that's a good record for me.

Nothing can capture the awe i feel during an eclipse. All the astounding astrophotography is gorgeous, but it's not the experience.  I don't plan to fly to Iceland or Spain for the next one -- but i'm urging my Dad to take his sweetie to see the total eclipse in the north of Spain. And if they offered to take me.... well, it's really tempting. The video tries to get some composite representation of the change in the light..

I've been working on the sciencey data collection and documentation, with a little frustration that it is slow going.

I'm disappointed that my work in putting a schedule in a timer app on my phone failed: i was using an exercise app that you can put in text that is read out and then the duration. I had "exercises" like "corona visible in 45 seconds" and it would read that out and then in the last three seconds of the exercise it would read out "three, two, one" and then read the next "exercise," "Corona." The time drifted. I think there's a few seconds between exercises. So i turned that off and "winged it." I hadn't brought my written out plan, so the different time lapse rates are not symmetric around the totality and  i turned off the camera before the eclipse was over.

I've spent this week fixing a four frames that had problems and figuring out what to do with some dropped frames. I'd forgotten to turn the power supply on for the aged GoPro, and it started beeping and turning off. I thought it was overheating, so i wrapped it in foil, getting two frames with significant foil in view. There were also two frames during totality where the camera took very short exposures (while recording full exposure times). I've adjusted the exposure (and a little color on the wind sock).All shades of my dissertation experiment where i spent years trying to get beamline contamination removed from the signal. One frame is still ugly, and it gets doubled due to missing frames: but it's good enough. I will not let perfection get in the way of completion over that frame.

The drops in exposure did get me thinking, and so i extracted metadata from the images and was able to extract the light level the camera shot for. I recognize both our eyes and the camera adjust to the light levels, so i didn't want to try and adjust all the exposures to give an objective sense of the actual change in light. Instead, plotting the light level the camera shot for with the temperature measured gives a nice sense of how the light change happens ahead of the temperature change.

This demo appears to have the graph synced with the video, but it is just proof of concept. It's "impressive" how folks animate the graphs. Essentially you are sliding a piece of virtual paper off the graph to reveal it. Hey, it works. I just need to get the rate change points lined up.

Yes! Things that I remember the most: the way that it got suddenly cold at totality; goosebumps cold so that the feeling of cold and awe and amazement were blended in my head. Also, the way that it got so quiet, and then two huge turkey buzzards flew up from the pines and flew crazy circles over our clearing. And they way that it felt that I could just rise up and fall into the nothingness. Definitely a portal.

Very cool video! Thanks.
