At work, we have been collaborating with the XRCT research team at main campus, and I thought these prints fitted in nicely. Of late, I seem to be taking more of an interest in the history of some of the imaging methods we use at work. These reminded me of the CT scan slices I’ve been trying to process with new software.

Both pictures have the name of the creator at the bottom, Dr A.G Peace.

The seller informed me that these came from a house clearance he did a few months ago. The original owner had been a teacher at Bolton School retiring from there 20+ years ago. His home had a lot of academic pieces, mainly books and journals, along with these pictures.
I can find an AG Peace in an article with GE Pringle from 1952 here.

Sadly, no photographs are included in the article but these prints must be related to their research.
I’m now thinking that CT scan data like this, and maybe photogrammetry point clouds might translate well into abstract analogue photographic print processes.
