Read the full tutorial on the site. Very good advice!

*&^%$# tourists, everywhere.

Throwing a snake in before you take the photograph is even better than photoshop.

But then the snake would be in the picture... Probably the safest way would be to hold up a sign "FREE LUNCH -->" - that should do the trick.

take a look at this online tool that does about the same automatically, with some interesting results.

Bets on how long Flickr will take to mimic it?

Does anyone besides me find the whole idea a little weird? I mean, presumably you've never even seen the place without tourists, right? Why is it so important to "purify" your photo?
