I stumbled across a group on Flickr the other day that does something called HDR photography. They're very bold photographs, with vivid colour range across-the-board.

Apparently, what you do is take several (apparently at least 3) identical shots of a scene, but at different exposures (i.e. -2, 0, +2; or -2, -1, 0, +1, +2). Then, using software such as Photoshop or a specialised progamme, you "merge" them together, taking different tones to create very dynamic photographs.

A better explaination: http://en.wikipedia.org/wiki/High_dynamic_range_imaging

And some lighthouse examples ("crowd favourites"):

I've got a possible little photo expedition planned for this weekend...and I'm going to try this out. I think it could be really, really cool to try out.
