The site itself has a wealth of information all in the one place to research, some will agree with it, some will disagree but its given as a resource for all to look at. http://www.mazal.org
I will post 3 photographs as a sample, I will comment here and then post below in order for easier reading.
Then first photo (i) is simply to show the scale of the camps, from viewing the readings here, many are unaware of the size and complexitiy of the whole area. It isnt topical, it is just an aerial photo from 26.6.1944
The second photo (ii) is topical, it is what could be called a "convergence of evidence" photograph.
It clearly shows a train at the siding, it shows people being seperated into distinct groups, one group heading for the part of the camp where the Gas Chambers and Cremortium are, (there are no exists from the direction they are heading.
Why is it a convergence? Deniers desperately try to treat things in strict isolation, deriding all eye witness accounts, claiming anything docmentary evidence is false it if affects their case. A convergence is a third party piece of evidence that ties in other facets. This picture is such a one. It corroberates all those eye witness testimonies from the Germans and prisoners who survived. It matches the plans of the camp as told by them.
The third picture (iii) is another convergence one, showing the dismantling of the camp in December 1944, again it fits into accounts from the Germans and prisoners who survived. It is at right angles to the previous one btw.
Heading of a standard attack, those who claim John Ball has disproved the photos as frauds, need to read this http://www.holocaust-history.org/auschwitz/john-ball/
A future essay on this website will address the specific issues John Ball raises. For now, we have seen nothing which indicates his expertise to speak on those issues. He can offer no academic credentials of significance. He refuses to address a contradictory expert opinion presented by someone with superior credentials, and has covered up this refusal with a fabrication. The one time he offered to stand behind his results, he quietly disappeared the moment real interest was displayed.
And the one time his expertise was put to any kind of real test - in a court of law - he was "stripped almost bare": ruled so unqualified that he could not be asked to render an opinion on anything related to aerial photographs of Auschwitz.
Detailed analysis of aerial photography is largely a matter of interpretation, and where the results are important we should not trust the interpretation to amateurs. When we are asked to take this man's drawings, explanations and theories as so authoritative that they can nullify the testimony of eyewitnesses to and perpetrators of the crimes, we are at the very least entitled to some evidence that he is well-qualified.
The evidence indicates the opposite.
Shades of Fred Leucter, a psuedo academic to try and mislead.
For more photos and a detailed examination of Ball, go to http://www.holocaust-history.org/see-no-evil/
Some will disbelieve prefering their own predjuices to knowledge, some will study, thats what the site is offered for, those with genuine interest to go and look and start to see for themselves.
The book on the subject is The Holocaust Revisited: A Retrospective Analysis of the Auschwitz -Birkenau Extermination Complex - Dino Brugioni and Robert Poirier (1979)
