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 think it's fascinating to see a comparison of the results of different people's efforts to process a single image, especially one of such marginal quality but such great significance as this one shot of Proteus (honestly, when does anybody think we'll get another chance to look at Proteus?) You each have a slightly different approach and a range of goals, as well as a range of willingnesses to accept the possible introduction of artifacts in order to generate a pleasing product. Yet all the approaches appear to be systematic (in that they should be reproducible -- no actual subjective painting, for instance). Anybody else want to try?
