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.

I have no way of knowing how much effort is involved in processing an image once a technique is developed. I have (don't laugh) HP image Zone on my PC and you just select a picture and click various settings on it and view the result. I am sure all of you are doing things much more advanced than that, and I have absolutely no idea how much effort is involved in restoring a particular picture once you have written some software to do it, nor could I have any idea unless specifically informed about a specific process.

I did not want to have anyone go to a lot of effort on one of my suggestions, but if it is easy to do, like I said, go for it. Don't anyone put themselves out on my account. I would never request someone put hours into trying out something I came up with, but if it s just a few seconds operation involving a click and drag, why not give it a try ?

Was not trying to be snide (just skirting topic of how dumb I am in regards to how computer image processing works) so apologies if that is how it came across.
