I figure that it is time for another thread like this. I still find it astonishing to see the versions of a lot of images that are reproduced over and over again. For example, this is the last mosaic of Triton taken before the close encounter began. The version on the Planetary Photojournal is on the left, my version on the right. Clearly, this image was produced as part of the "instant science" campaign. They did a superb job getting images to the public in a speedy manner, but they are extremely rough, since the team was busy running the spacecraft. However, it is this version that keeps being recycled. Worse, the version on the photojournal is clearly scanned from a printed copy, causing further degradation.
Here is a similar comparison, this time using Proteus (still 1989N-1 on the Planetary Photojournal!).
This discussion started in the thread about Viking crescents but was getting off topic, so I thought I would start a new thread here. -------------------- |

The Mariner 6-7 images on that site have a few issues, but they are pretty good. If I ever actually have time to work on an image again, I need to finish my Mariner 6 and 7 set. Here is my recent blog post related to this http://planetimages.blogspot.com/2009/09/m...ni-in-1969.html

QUOTE (tedstryk @ Nov 13 2009, 04:26 AM)  The Mariner 6-7 images on that site ( http://ser.sese.asu.edu/M67/mar67.html ) have a few issues, but they are pretty good. I have many objections to this web page, image gallery is incomplete and unsystematic. For example, I can not understand why there no picture 6N01. Secondly, images 6N02 and 6N03 (for example) are at different stages of processing. Properly it should look like this, showing the successive stages of processing: 6N01
6N02
If they are presented only selected images, all images in the gallery should be on the same stage of processing. You can see how great the differences in the various stages of processing. -------------------- Free software for planetary science (including Cassini Image Viewer).
