Automated removal of non-static elements with Photoshop
This is a short little video that demonstrates a quick and easy way of removing unwanted elements from your photos. To do it yourself, you’ll need several shots of your target - enough so that any area covered in one photo is uncovered in another. Once you’ve got that, Photoshop can automate the alignment and image compositing, to remove all those pesky people from your shot.
I found this through Stumbleupon, so I don’t know the full backstory / accompanying materials, if anyone would care to inform me!
