And invent it <i>right before</i> they post it? Oh, oh, I take that back: invent it right before you read it? Is that the new standard, because I missed that memo.

Wow. I was messing with PySight on my Mac a few months ago and wrote a filter that does this with video from the iSight camera. It looks for pixels that change and figures out what the background is. So if you fire it up while sitting in front of your computer you appear until you start to move. Then parts of you disappear as you reveal the background. New people walking into the room never appear unless they hold still for a while and are detected as background. Somebody wrote a master’s thesis on this? Wow.

Only non and few moving objects and people manifest in the pictures/videos. We don`t want to filter every person out but try to find something inbetween by adjusting the variables in our programming (max/msp/jitter). We also refer to to Daguerre photo mentioned above.

Didn't BB report a while back on a site where you can upload a number of photos taken of the same view, and it remove everything in motion? “Nobody can be so amusingly arrogant as a young man who has just discovered an old idea and thinks it is his own.”

Just take the 2-5 images you need, slap them in Photoshop as layers, and then erase where necessary. Eventually you'll have a photo of said attraction without any dipshits cluttering the beauty of what you were shooting. Works best with a tripod, but a steady hand can do the job. …Actually, I use this trick all the time when taking pictures of outdoor attractions, where inconsiderate idiots and/or their festering excuses for offspring are oblivious to and/or clearly aware of the fact that I’m trying to take a picture and walk in front of the camera.

He's in the lower left, with his leg raised. The photo should show a busy street, but the motion of the people and carriages have made them vanish into time. The image of the one man survives only because he is standing still, probably having his boots blacked by a phantom street urchin.

Not sure how you can get a master's thesis out of ancient technology, but I'm sure there's always a new feature. Antinous, you might need to relax before you notice that everyone on the Internet is wrong...
