Having just got back from a conference which contained a lot of lab physicists showing their experimental setups, I have observed two main genres of physics lab photography, which are:
Picture meant for their own records that's breached containment, taken under harsh fluorescent lab lights on a phone. Very often poorly centred/cropped, sometimes with half a blurry graduate student in shot. Backrooms lighting and general liminal vibes. These pictures have the power to make a rack-mounted oscilloscope seem ontologically evil
The bisexual lighting dutch angle professional shot. These usually happen with experiments that the company/university deem Big and Important, so they get a professional photographer in as part of a press release about the project. They darken the lab and set up lights worthy of a high school drama production and sometimes a smoke machine. If lasers are involved in the experiment they love to turn on the visible light alignment laser on the optical table, with the smoke machine smoke to make it look Cool. The PI of the experiment will be sitting there staring glamorously and wonderingly up at the equipment and pretending to work on Science™, while they look like they're at the club. This will be published on the website forever and ever
My theory is that all lab photography exists on a spectrum between these, possibly with another as yet undetermined axis. Also, very important: both of these will be pasted, blurry and pixelated at the wrong aspect ratio, on everyone's powerpoint presentations at conferences. This, perhaps, is the great equaliser
