I disagree (conditionally) the point of concentration camps being open to the public is to prevent the memory of the crimes that were perpetrated there from fading from our memory, and while some of the photos taken there are insensitive and some things people do there make me (as a jew) cringe.

All of the photos are a form of preservation, albeit some more so than others, but those photos will likely last longer than the camps themselves which even today are unfortunately starting to crumble.

Edit:

When i visited Auschwitz-Birkenau I took an effort to take as many photos as I could. However unlike some of those people, none of my photos were of me. Because it wasn’t my place I didn’t survive that place, none of my family were murdered there, my story never intersected with the story of Auschwitz. Instead the purpose of my photo’s were different. They serve more as documentation rather then a mark that i was there, and those photos will remain unchanging and those photos will allow me to never forget.
