Mike, what is JNCE_2020259_29C00004_V01 testing? It was supposed to be a Ganymede image, but since it didn't contain Ganymede they changed the title to reduce confusion. -------------------- Disclaimer: This post is based on public information only. Any opinions are my own.

Those images are post-processed examples of these reprojections.

Some initial PJ29 detail images. With the perijoves becoming more northerly, we're getting clearer images of the northern filamentary region, though at the expense of sharp southern views.
I'm a little disappointed with the color I'm getting in the Northern latitudes, though my pipeline tends to white-balance the color channels, which I'm usually ok with (I'll leave the amazing true-color work to Bjorn)...

And two fish-eye 'marble' composites so far:

Beautiful work Kevin, the Jupiter 'marbles' are my favorite Juno compositions.

I'm therefore going to revisit some of the color tests/calibrations and among other things compare the PJ29 color to earlier images. So I'm very curious to know what you are disappointed with. Does your pipeline white-balance the images/color channels differently in different images or do you multiply the R/G/B values with the same fixed values for all of the images? |

My process uses the same values and conversions for every image, such that I can output close to true color on the output side if I wanted to. But I tend to just use a proportional stretching method when I convert from the ISIS3 cubes to tifs which in effect white balances them (though not on any specific value white). I've done rather little to validate the 'true color' output, so I don't really use it.

Here is a list of links to intermediate PJ29 renditions I've uploaded thus far.
I might update that link list occasionally if time allows, probably also with links to other PJs. |
