I think these new domains are a bit pointless. They're too long to remember and more that half the world will have issues spelling the word photography (due to not knowing English or poor spelling). If it was .photo then you might stand a chance, but otherwise it makes your domain really long. .photo is apparently an option, but so is .photos, which could lead to people going to the wrong site and you'd probably have to register .photo .photos and .photography just to be safe.
The general public will probably have issues understanding that the web address you are giving them is
www.whateveriwant.photographyI will probably just stick to .com
If someone has already registered the .com you want, then it's likely that most of your users will find their site before yours.
