Image PJ15_43. The left version is an approximately true color/contrast image. In the version at right the effects of the varying illumination have been removed.

Attached Image


This image was processed with a new version of my JunoCam processing pipeline after I fixed an annoying bug that was usually not of significance but could occasionally result in some color misalignment near the limb. This had to be fixed during postprocessing - not having to fix this misalignment saves a considerable amount of time when processing the images where this problem would have occurred.

By JunoCam standards this is a fairly distant image as this subset from the metadata shows:

IMAGE_TIME = 2018-09-07T02:21:50.387
MISSION_PHASE_NAME = PERIJOVE 15
PRODUCT_ID = JNCE_2018250_15C00043_V01
SPACECRAFT_ALTITUDE = 103371.3 km
SPACECRAFT_NAME = JUNO
SUB_SPACECRAFT_LATITUDE = -78.5043
SUB_SPACECRAFT_LONGITUDE = 66.4235
TITLE = PJ15 Southern timelapse sequence
Resolution at nadir: ~70 km/pixel

Amazing how far into the twilight-dark you get before it come apart. Very nice.

The second image has lots of interesting details. The enhanced version of it has been processed to enhance both large scale and small scale features by using processing parameters that differ for different parts of the image, depending on the contrast and the amount of small scale details in the original unenhanced image.

And a subset of the metadata:

IMAGE_TIME = 2018-09-07T01:20:45.235
MISSION_PHASE_NAME = PERIJOVE 15
PRODUCT_ID = JNCE_2018250_15C00030_V01
SPACECRAFT_ALTITUDE = 6252.9 km
SPACECRAFT_NAME = JUNO
SUB_SPACECRAFT_LATITUDE = -7.3210
SUB_SPACECRAFT_LONGITUDE = 347.0286

I was curious for a processing pipeline comparison, so I did up the same angles as posted by Bjorn on Sunday.

As typically output by my pipeline:
[attachment=43488:JNCE_201...pare___1.jpg][attachment=43489:JNCE_201...pare___2.
jpg][attachment=43490:JNCE_201...pare___3.jpg]


And enhanced using my normal methods (Photoshop + Lightroom)
[attachment=43491:JNCE_201...re___1_2.jpg][attachment=43492:JNCE_201...re___2_3.

Hi Kevin. Your image at http://www.missionjuno.swri.edu/junocam/processing?id=5628 has a little green artifact on Jupiter's limb (at about 1 o'clock). It's not visible in the raw images. I wonder what caused it. It's been spotted by UFO "spotters". ph34r.gif
