I used to do the photo-finish at the local (regional area) races. Sit in a box for an afternoon, read a book or hack some code for half an hour to 45 minutes. Then watch the race, hold down a button as the horses cross the line, drag line-markers onto the horses noses on the image, mark up the number, print a copy, save to disk, go back to reading until the next race.<p>Collect $AU200 for an afternoon's reading, basically.<p>Lost the gig during COVID; easy-come easy-go.<p>(The camera was actually super-interesting: it's like a slit-scan camera, it records a pixel width image continuously and adds it to the last image taken. So if a horse passes the camera, it takes a photo of a sliver of the nose, then then next sliver of nose a split-second later, and so on. It's sort of like taking a picture of time, rather than space. Very cool).
