Yes, the resolution between the different photographic systems on the various probes is noted, but doesn’t qualify as a discovery of change. With out assumptions of any kind and with out the need of a trained eye most people can see changes between photographs taken over time, if there are changes.
FieryIce and I are jointly conducting this investigative thread into possible Mars changes as shown in the photographs taken over the past few decades, and as stated in her first post. These are not the only before and after pictures available on the web and the others should be investigated along with what we posted here. As this thread develops we will be posting links to other pictures on the web for perusal. It is our hope that others will find photos that we haven’t listed that will add to this topic.
We have added the grid for orientation ease of discussion for changes discovered.
