Regarding print size and resolution: Chronophotographs have a time based minting mechanism; they vary in resolution; the earliest mints are low res, with later mints growing in resolution to an absurd level. Within the collection so far, the resolutions vary from 200x200 up to 15000x10000.
In general, artistically aiming to keep the low-res ones smallish and the high res ones large. I aim for print resolution of 250-300dpi. Below 200dpi you start to perceive pixelation/bluriness. That's an acceptable tradeoff for the smaller low res Chronophotographs to make them an acceptable size, but don't expect a huge print for an early epoch Chronophotograph.
