The first prize is a Canon Powershot S90, Canon WP-DC35 Waterproof Case (worth around USD200/- and is rated for a depth of 40 meters!) and the Canon Selphy ES40 photo printer (which of course can’t be used underwater =). How can you win it? Visit The Powershot S90 Street Photography Challenge for further details!
In short, you don’t need to be a Canon user, it is open since 23rd October and the closing date is end of this year (actually 29th December 2009), limited to 3 entries per participant (from the following countries; Bangladesh, Brunei, Cambodia, India, Indonesia, Malaysia, Maldives, Myanmar, Nepal, Pakistan, Singapore, Sri Lanka, Thailand, and Vietnam) and submission is to be in JPEG with a file size of not larger than 1MB.
I personally find the 10 tips interesting but I guess most people will probably not be adhering to tip number 2 (use a compact camera!) as most photographers will have a DSLR handy.
By the way, the Canon S90 is very similar to the Canon G11 and it is reviewed against the Sony WX-1 here.
