Sonderkommando photographs
The photographs were numbered 280–283 by the Auschwitz-Birkenau State Museum. Numbers 280 and 281 show the cremation of dead bodies in a fire pit.  Number 283 just shows trees (since the photographer could not see where he was aiming the camera, he aimed too high for this photo).  Number 282 shows a group of naked women just before they went into the gas chamber.
