I noticed this interesting description of the PJ46 JunoCam imaging at the Juno website:
QUOTE We are collecting more methane images than usual. A lot of data volume is planned for lossless compression images to avoid compression artifacts. This is going to be interesting and should result in considerably better images, at least in relatively dimly lit areas. |

I don't know if the uncompressed images will be used for all filters, but a methane filter is very narrow and most of Jupiter is pretty dark with one, so sending uncompressed images will be particularly helpful for the methane images.

I noticed this interesting description of the PJ46 JunoCam imaging at the Juno website: Images started showing up at about 6:25 PST tonight.This is going to be interesting and should result in considerably better images, at least in relatively dimly lit areas. I see 9 HUFFMAN in the color images I've downloaded so far, which are in range PJ46_75 to PJ46_136. Edit: Looks like rest of images are in approach/departure "movie" collections which don't contain additional HUFFMAN compressed images. And here is PJ46_116 (crop exaggerated color/contrast) |

First pair of processed images from Perijove 46. I used two different processing pipelines for each. Both were then put through the normal wringer of Photoshop, Topaz SharpenAI, and Lightroom.
This one was processed with my traditional USGS ISIS pipeline: Jupiter - PJ46-80 This one was processed using my newer simplified pipeline: Jupiter - PJ46-112 - Detail |
