Given how severely imperfect this approach is, I’d much rather people didn’t use it: it’s disconcerting and distracting. Either do it properly (which tends to mean chroma keying, preferably with thoughtful handling of lighting too if you do anything like background <i>replacement</i> rather than just removal), or don’t do it at all.<p>I have not the faintest clue whether this position of mine is popular or unpopular.<p>Better models may improve matters (the one shown here looks to be decidedly worse than some), but even the best I’ve observed at this time is still something I’d prefer not to be used, because it’s still wrong too much of the time in annoying ways.
