I did a job developing a multimedia CD that trained doctors. Well, it was more of a marketing tool. For oncology… of the face and genitals. It was easily the most harrowing experience of my career. So many genitalia and tongues with hideous growths and what have you. The people who agreed to be photographed were both brave and very, very unwell.
I was on the tech team, sonI got off quite lightly. The two graphics people spent day after day aligning and processing these photos so that everything was clearly visible. I don’t know how they slept at night.
I left after a year. I don’t think anyone managed longer than that.
There’s a great German TV show from a few years back about a crime scene cleaner “Tatortreiniger”. It’s more philosophical/funny than gruesome and worth a watch if you don’t mind reading sub-titles. The BBC did an adaptation in English, but I’ve not watched it yet.
