Only problem is that nasa claims to provide raw photos, but yet at least some of them appears to have been altered.

That's exactly what I did not do. I did not run it through an editing program. I ran it through software used in science.
Also you cannot run a tif.file through an error level analyzer. ELA only works on JPG format. So it is pretty logical that you cannot see the manipulation.
It is worth noting that edges and areas red in colour are often depicted as brighter in the ELA tests. This due to the way the photos are saved by various programs. It is not proof that image was manipulated.
If you are unsure how to interpret the results, please do not claim the results of this tool as proof of anything.
"Error level analysis will find the manipulation ... despite how well you try."

Now why would an error level analyzer only work with a jpeg? You are aware a jpeg is a lossy reproduction process aren't you, of course an error level analyzer is going to find errors! Because a jpeg compresses and stores algorithm passes of 8 by 8 pixel square areas.
