JunoCam Citizen Science

My first attempt at Citizen Science on display in the dome!

A few weeks ago, I watched this video, produced by the Griffith Observatory a year ago:

As in the demonstration video I watched, I used Gimp. Of course I could have used Krita, but Gimp is my go-to since I’m so familiar with it.

First I downloaded set of images from 2021-07-21 Perijove 35:

https://www.missionjuno.swri.edu/junocam/processing?id=11074

I opened the three color PNGs as layers and colorized them accordingly.

Then I played around with the individual layers’ brightness and contrast settings, then combined using Screen as the blend mode.

After I got the colors close to how I liked them, I used the G’Mic Tone Sharpening to bring out the detail. (https://gmic.eu/index.html)

I spent very little time on it, about 25 minutes total. I’m pleased with it and look forward to showing others how to make their own.

And that episode title sounds better than the one I used in the recording. In any case, this week is ~~some rambling from me in which I complain about stuff and complain about complaining about stuff~~ some insightful thoughts on some of the ups and downs of using FOSS.
