Juno perijove 27, June 2, 2020 Options

[Bjorn Jonsson]

Many (but not all) of the images from perijove 27 are now available. This is image PJ27_36 in approximately true color/contrast and enhanced versions:




North is to the left in the last two images but in the other images north is up.

An interesting feature in the last image is the long, narrow and slightly wavy red band running from upper right down to the bottom of the image a bit left of center (it is also visible in the true color/contrast version but it's not as conspicuous there). The visual impression is that this is transparent, reddish haze and that the clouds below the haze band can be seen through the haze. It will be interesting to see what's happening farther west (down in the image) but the images showing this are not yet available at the time of this writing.

The enhanced images are a bit experimental. Compared to what I usually do, I'm using a somewhat different method to increase the contrast and exaggerate color differences. Also I'm now using DeNoise AI from Topaz Labs to reduce noise and sharpen the images. This is an awesome tool in most cases but one must be careful not to overprocess the images. There are also some 'types' of images where it doesn't work well - I tried using it to process a very noisy grayscale Galileo image of Europa with horrible results. But I've been getting great results so far with the JunoCam images - far better than in e.g. Photoshop.
