Generating contact sheets on macOS

Recently, I have been undertaking the enormous task of scanning my father’s extensive collection of photographic negatives. The idea is to ensure their longterm survival, with the bonus of (re-)discovering gems among them. But archival quality TIFF files do not make for an easy browsing experience, so I was looking for a way of creating low quality “contact sheets.” This proved a lot harder than I thought, but I found a fantastic solution.

Driving 4K

Through a series of events which I won’t go into, I ended up giving up my 5K iMac to my wife and making do with a 2016 model MacBook Pro 13″ with TouchBar. The MacBook Pro is slightly less powerful (according to Geekbench) than the iMac, but I wasn’t too concerned about that. What caught me out was the display situation.
