Removing people from images with a big stopper: after
An experiment in using long exposure to make people disappear. Taken on the Castle Explanade as sunset approached, and this shot was in shadow, i.e. pretty dim. This shot was taken at f8, ISO 50, and 64 seconds. It has erased almost everybody from the scene. There still a kind of patchy dark mistiness along the people trail. Plus a ghostly foot from someone who stood around for a bit while shifting the other foot. Plus a patch of orange glow, and another of lime green, from fluorescent jackets which paused for a chat.
The big stopper used was the peculiarly cheap & as far as I can see peculiarly good, in fact excellent XCSource 10 stop ND filter. 64 secs divided by 1/6th sec is 384. This shot was underexposed by about 1.5 stops, boosted in post processing to the same exposure. I wanted a quick test result more than complete accuracy & best IQ. 384 x 2^1.5 = 1086, close enough to the 1024 of 10 stops for experimental error. 10 stops filters are sometimes a stop or two short of 10, but this one looks close enough.

The woman of a passing couple was a bit worried that "her ugly face" (as she jokingly put it) might have appeared in my photograph, which she feared might be published. She was both delighted and startled when I showed her there was nobody at all in my photograph :-)
