I’ve been tracking the most insane photographic anomalies at a cemetery since 2003 with different photographers and different cameras. Each time I go, something new shows up for us. There are just too many to show them all. Same place. Different times, years, photographers, cameras. You can take pics and it will develop over frames and then fade off, the longest shooting time was about 2-1/2 minutes. Same family grave with about 20 members buried there.
