So, what do you do if you've got a big heart, an empty wallet (after buying that fancy Leica), and a lot of creative people in the same room? You create a book, of course, celebrating some of the most awesome photography by your users - and raise some money for charity at the same time.
Well, that's what the Leica Users Forum did anyway, aiming to repeat the success from previous effort - their first book was published in 2010 and raised over £12,500 / €15,000 / US$19,500 for their chosen charity, The Association for International Cancer Research.
And now, of course, they're doing it all over again.
This year, they've selected their 100 best photographs submitted to the judging panel.
Interestingly, even though all the photos were taken on Leicas, more than 20 different camera models were used to take photos, and yet, only 13 of the shots in the book were taken on film - the rest were taken with the Leica M8 and M9 digital rangefinder cameras.
So far, the 2012 Book has raised nearly £4,000 already, so if you want to be part of history, ogle a lot of fabulous photos, and help fight off cancer in the process point your browsing device at the Blurb page for the book, and dust off your credit card.
The photos are gorgeous, and the cause is good. What are you waiting for?
