I did notice the majority of the distant pictures of Phoebe appear over-exposed. The RAW image FAQ states they haven't been processed in any way, so what exactly happens to these RAW images before they're placed on the web?

They get..umm. processed They have to be - most of the images taken are 12bit images - and a JPG can only be 8bit - so there HAS to be processing by default. That processing is done automatically I assume - and the algorythm for it is a bit stupid - it just takes the brightest thing in the scene and makes that white, and the darkest thing in the scene and makes that black - and interpolates ( badly ) inbetween.

If it was done more intelligently, we would see moon detail - I am sure. You dont build a multi-billion $ spacecraft, fly it billions of miles, and then get your exposures THAT wrong
