Researching the horrors of Auschwitz set this photographer on a hunt for his lost family history. Philip Key reports

Indeed, the largest number of visitors are from Britain.
 
There are some myths about Auschwitz which he is pleased to dispel. It has been said, for example, that no bird sings in the camp today.
 
Untrue, says, Guy, "There are birds there and I photographed some but there are not many. The simple truth is that there is little food for them."
 
Another tale has that ponds in the area are clouded with the ashes of the dead. "That is true. The camps were built on a swamp and the ashes of so many dead do still cloud the ponds."
 
On both trips, Guy was given special admission to certain places including areas where items are seen only behind glass. He was able to get in among the discarded shoes. "Behind the glass there is no smell but when you stand among them, you can still smell the people."
 
There were unnerving moments for him like when he was setting up one photograph.
 
"I realised I was standing at the edge of a mass grave. It looked like a bowling green."
 
He also went to look at the factory run by Oskar Schindler using slave labour made famous by the film Schindler's List. This too has become a tourist attraction although when he was there it was shut up.
 
"I met a security man and talked my way in," he explains. "I am after all a Liverpudlian." He did the same on a second visit with a different security man, that time helping a visiting Welsh man inside with him.
 
At Auschwitz he photographed the place in the snow, noticing how the blue sky was reflected in it. And there also was the notorious entrance to the camp bearing the legend "arbeit macht frei", translated as: "work will set you free".
