Reprocessing Historical Images - II, Restoring images from antiquated and/or poor quality sources Options

[tedstryk]

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.

Ted -- is it true that Endeavour Crater is resolved in these mosaics?

I can see a slight darkening where Endeavour is, I think. The craters in the neighborhood which are either slightly larger or more distinct all show up quite well.

It's a great view.

Yes, it is a barely detectable smudge. However, while the Mariner 7 view is in my estimation prettier, Mariner 6 got a better view of this region and it is much clear in this mosaic.
